CHAPTER 2 CONTINUED

Secretary Terasaki Established Net in South America

As a result of the conference of Mr. Terasaki with the Japanese Ministers of Argentina, Brazil, and Chile, Tokyo was informed on August 22, 1941 that the establishment of an intelligence network in Latin America had been proposed to secure information in the United States. Spies would be placed within the United States, American propaganda as revealed in printed matter and radio broadcasts would be analyzed, and intelligence secured from sources in Latin America would be collected and evaluated.

No. 643

(Part 1 of 3) (Message to Tokyo #230)

From TERASAKI.

The results of my conference with the Ministers to Brazil, Argentina, Chile, and_ _ _ _are as follows:

1. We propose an (intelligence) set-up in Latin America in order that we might secure intelligence on the public opinion of the United States, her situation militarily and diplomatically. The method by which this is to be accomplished is roughly as follows:

a. We propose the establishment of spies within the United States. From these we shall obtain secret intelligence.

(1) This set-up shall perform the duties of collecting and evaluating information obtained from the offices and personnel of American ministries in Latin America.

(2) It shall study the effectiveness of the propaganda contained in American and Latin American printed matter and radio broadcasts.

(3) It shall collect and evaluate intelligence secured from persons with whom they are in close contact, as well as the offices of third-powers in Latin America.

(4) It shall collect and evaluate intelligence secured from individuals and government offices in Latin American countries.

2. Though we plan for the organization of an intelligence net and the distribution of agents necessary for the operation of these proposed steps, in light of current affairs when anything of great importance arises, we, of course, will put every detail into operation with the effectiveness with which it is carried out in spy stories.

Japanese Espionage Network Begins Operations

In line with the establishment of an efficient Japanese spy organization in South America on 22 August 1941 by Mr. Terasaki, the Japanese intelligence coordinator for the Americas, all Japanese offices in North America were ordered to give their immediate attention to the selection of qualified espionage agents. Among the spies was a seaman who was to be placed with some prominent steamship company servicing North American ports.

Foreseeing difficulties in selecting reliable individuals and in checking information derived from foreign countries, Mr. Terasaki emphasized the necessity of Japan's spending vast sums to procure men and administer the whole intelligence network. Combating American counterespionage activities presented a problem since FBI agents were known to be attempting to gain the confidence of those employed in the office of the Axis nations. He urged, therefore, that all Japanese agents be selected with care.

Each Japanese office in South America was to be equipped with radio sets capable of receiving US domestic broadcasts. Moreover, a central listening post would be located possibly in Brazil, where a secretary proficient in English shorthand would be on duty at all times. It was learned later that American broadcasts would not reach beyond 1,000 miles. This made it impossible to establish a post either at Buenos Aires or Rio de Janeiro to listen to broadcasts made in the United States.

Subscriptions to American papers and magazines were to be procured in the name of a South American for analysis by trained Japanese agents. Important spy centers were to be located in Brazil, Argentina, Chile, and Colombia, the latter country was of importance because of the nearness to the Panama Canal. It would be necessary, therefore, to enlarge the telegraphic sections of all Japanese offices and to use the intelligence sources supplied by the local Domei news agency, special correspondents, and Spanish and Portuguese language correspondents. Japanese merchants would be employed to keep the organization informed of economic conditions in the United States. If the Axis diplomatic staffs were ordered out of the country before the Japanese, their German and Italian informants would be hired. Not only were Latin American spies to be used, but also those who lived in Spain and Portugal, since it would be possible, should Mexico enter the war, to relay information from Mexico to Spain where it could be retransmitted to Japan.

Regarding paragraphs 1 to 3-a of my message #231.

All of our offices in North America should give their immediate attention to the selection of spies. They should choose only those who are best qualified for the job and have them go to work on collection of information and, if possible, liaison. The offices in Latin America shall accept those reports from them in which they can place credence. If it is possible to obtain the services of an informant who has been a seaman, it might be a good plan to try and get him a job in a steamship company. (There is one who falls in this category in New York. It would be very much to our interest if a job could be found for him in some steamship company which as a North American service.)

It must be borne in mind, of course, that it is exceedingly difficult to select individuals who can be reliably utilized. Moreover, it is very difficult to check any information from a foreign country. Therefore, it is of primary importance that we make up our minds to spend vast sums of money.

It is a known fact that the F.I.B. (F.B.I.?) is making a practice of trying to get its men into the confidence of those in the offices of the Axis nations. Please note this point carefully and exercise the utmost caution in making the selections.

The matter contained in (b) of the above referred section, would be next to impossible to put into effect. However, if there is one with whom very close relations have been maintained in the past, it may be that he could be utilized.

With regard to (c) of the same section, each office should be equipped with good radio sets of the middle wave band. They shall be used to listen to domestic broadcasts in the United States. The central listening post shall be located, let us say, in Brazil, where one who is proficient in shorthand of English shall be on-duty at all times.

The leading U.S. newspapers and magazines shall be subscribed to now in the name of some foreigner. These shall be thoroughly perused (even to the society columns) and carefully analyzed.

The intelligence officers referred to in section 4 of the same message shall be stationed in Brazil, Argentina, Chile, Colombia, (the last mentioned is looked upon as a very important post by our Army and Navy, with a view to obtaining information about Panama, as you are already aware), and Mexico.

To fulfill all of these duties, the telegraphic section of all of those offices concerned will have to be considerably enlarged. This is at present the most important actual step to be taken.

As sources of supplies for the above mentioned intelligence personnel, the present sources of Domei news agencies and others of our special correspondents shall be utilized. We shall also make indirect use of the Spanish and Portuguese language correspondents.

Since it will be of interest to keep abreast of the economic conditions in the United States, we shall maintain close contact with our merchants who in turn will keep themselves advised through local native merchants who have access to the information in the United States.

Should the German and Italian diplomatic officers be ordered out of a country before the Japanese, we shall make arrangements to take over their informants.

The informants referred to above shall not be limited to Latin Americans but shall also include those who reside in Spain and Portugal. (Should, for example, Mexico get into the war, our informants in Mexico shall relay their information to those in Spain and Portugal who in turn shall pass it on to Japan.)

According to what the specialists say _ _ _ _broadcasts do not reach any point beyond 1000 (miles?). I understand that even with a good receiving set it is impossible to listen in here or in Rio to broadcasts made in the United States.

Japanese Naval Officials in Mexico Disapprove of Furnishing General Intelligence

To Foreign Minister Togo's inquiry whether the office in Mexico had begun the work of furnishing general information, Ambassador Miura replied that he had discussed this matter with his Naval Attaché and had subsequently wired the Chief of Special Service Section of the Naval General Staff. Although at present they were waiting a reply, he pointed out that because of the necessity of maintaining the security of the "L" organ, the naval authorities disapproved of furnishing general information. He asked that the Japanese Foreign Office discuss this matter with Navy and subsequently wire its decision.

Eight days later Foreign Minister Togo declared that general intelligence was to be distinguished from naval intelligence in that it was used for reference purposes by the Foreign Office. He was instructed to reorganize his office immediately for the collection of general intelligence.

Ambassador Nomura Sends Representatives to "America First" Meeting

Ambassador Nomura informed Tokyo that he had rushed Secretary Terasaki to New York on October 30 for the meeting of the America First Committee. There the intelligence agent has met_____(Comment: DoD withheld name). Secretary Terasaki asked _____ (Comment: DoD withheld name) to tell Colonel Lindbergh, who was for "America First," that the United States was about to fight with Germany concerning its policy of "Britain First" in the Atlantic, and with Japan under its policy of "China First" in the Pacific. He commented on the fact that a crisis was at hand between Japan and the United States and that the American people did not understand the reason for such a war, although, fundamentally, it would be due to the China problem. Secretary Tarasaki had further stated on this occasion that it was a mistake to think that Japan would give in if it were driven into a tight corner by the United States. It was necessary to view realistically the situation in the Orient, since it was most inconsistent to fear a southward push by Japan and at the same time to cut off her petroleum supplies.

As the American First Committee was meeting in New York on the night of 30 October, I rushed Terasaki up to New York on that date. He met with (an associate of officials of the Committee). (As the American First Committee is being watched by the F.B.I. this must be kept strictly secret.) After commenting on the fact that a crisis is right at hand between Japan and the United States he told _ _ _ _that he would like to have him tell Colonel Lindbergh, who is for America first, that, while the American people do not understand the reason for such a war, it has to do with the China problem, that the United States is about to fight with Germany over her policy of Britain first in the Atlantic, and with Japan over her policy of China first in the pacific. _ _ _ _consented and later the same evening he said that he had told him.

On this same occasion Terasaki also strongly asserted that it is a mistake, based on a misunderstanding of the Japanese psychology, to think that Japan will give in if she is driven into a tight corner by the United States, and that even as the United States is adopting a realistic policy in regard to Central and South America, it is also necessary to take a realistic view of the situation in the Orient, and that it is most inconsistent to express fear of a southward push by Japan, while at the same time cutting off petroleum supplies.

Frequency of Ship Movement is Left to
Discretion of Consul

Since intelligence reports of battleship movements were made once a week, and the vessels could have traveled far from the vicinity of the Hawaiian Islands in that interval, Consul Kita was instructed by Tokyo to use his own judgment in reporting such movements. In addition, the Consul was asked to note the entrance or departure of capital ships and the length of time they remained at anchor. This dispatch of November 28 was translated on December 8, 1941.

According to a dispatch transmitted on November 29 and read by United States translators on

December 5, Tokyo requested that, in addition to giving reports on ship movements, Japanese officials in Honolulu report even when there were no ship movements.

Intelligence of this kind which are of major importance, please transmit to us in the following manner:

Japanese Continue To Watch Navy Maneuvers

From December 1 to December 6, 1941, Japanese intelligence dispatches were transmitted regularly to Tokyo. On December 1 a significant dispatch reported that ship maneuvers were held approximately 500 nautical miles southeast of Honolulu, with the battleships leaving Tuesday and returning Friday or leaving Friday and returning Saturday of the following week. It was noted that the fleet had never sailed westward or headed for the "kaiui" straits northward; the sea west of the Hawaiian Islands was not suitable for ocean maneuvers. The estimate of distance was based on the fact that fuel was plentiful, long-distance high speed possible, and the guns could not be heard at Honolulu.

(In 2 parts complete.)

Re your #119.

Report on the ship maneuvers in Pearl Harbor:

1. The place where practice maneuvers are held is about 500 nautical miles southeast of here.

Direction based on:

(1) The direction taken when the ships start out is usually southeast by south and ships disappear beyond the horizon in that direction.

(2) Have never seen the fleet to westward or head for the "KAIUI" straits northwards.

(3) The west sea of the Hawaiian Islands has many reefs and islands and is not suitable as an ocean maneuver practice sea.

(4) Direction of practice will avoid all merchant ship routes and official travel routes.

Distance based on:

(1) Fuel is plentiful and long distance high speed is possible.

(2) Guns cannot be heard here.

(3) In one week's time, (actually the maneuvers mentioned in my message #231 were for the duration of four full days of 144 hours), a round trip to a distance of 864 nautical miles could be reached (if speed is 12 knots), or 1152 miles (if speed is 16 knots), or 1440 nautical miles (if speed is 20 knots) is possible, however, figuring on 50% of the time being used for maneuver technicalities, a guess that the point at which the maneuvers are held would be a point of about 500 miles from Pearl Harbor.

2. The usual schedule for departure and return of the battleship is: leaving on Tuesday and returning on Friday, or leaving on Friday and returning on Saturday the following week. All ships stay in port about a period of one week.

In view of the present situation, the presence in port of warships, airplane carriers, and cruisers is of utmost importance. Hereafter, to the utmost of your ability, let me know day by day. Wire me in each case whether or not there are any observation balloons above Pearl Harbor or if there are any indications that they will be sent up. Also advise me whether or not the warships are provided with anti-mine sets.

 

Mr. Fuji Changes American Ship Maneuver Signals

On December 3, 1941, Ichiro Fuji informed the chief of the #3 section of Military Staff headquarters that he wished to change his communication signals for American ship maneuvers. Signal one would mean that the battleship divisions included some scouts and screen units and were preparing to sortie; signal two that a number of carriers were preparing to sortie; signal three that all battleship divisions had departed Hawaii between December 1 and 3; signal four that several carriers had departed between December 1 and 3; signal five that all carriers had departed between December 1 and 3; signal six that all battleship divisions had departed between December 4 and 6; signal seven that several carriers had departed between December 4 and 6; and signal eight that all carriers had departed between December 4 and 6.

A house on Lanikai Beach would be used as a signal station and would show lights during the night. One light in the window between 8 and 9 P.M. would denoted signal one, one light between 9 and 10 P.M. would mean signal two, and so on; two lights between midnight and 1 A.M. would signify signal five, and so on. It was further explained that if there was a star on the head of the sail of the Star Boat it would indicate signal one, two, three, or four; if there was a star and the Roman numeral III, it would indicate signal five, six, seven, or eight.

Also used at night would be the attic window of the Kalama House, located on the east coast of Oahu, northwest of Lanikai. A similar system was to be used; for example, if the window was lighted between 1900 and 2000, it would indicate signal three, between 2000 and 2100 signal four, and so on.

In addition, signals would be transmitted through the regular broadcast station in Honolulu. For example, if a radio advertisement read, "Chinese rug for sale, apply P.O. Box 1476," it would indicate signal three or six, whereas the advertisement, "Beauty operator wanted, apply P.O. Box 1476," it would indicate signal five or eight.

In case the light or broadcast signals could not be sent from Oahu, the signals would be given by bonfire daily on Maui Island until the Japanese "EXEX" signal was received. The signal bonfire would be located at a point halfway between lower Kula Road and Haleakala Road and would be visible from seaward to the southeast and southwest of Maui Island. If the fire was seen between 7 and 8 P.M., it would indicate signal three or six; between 8 and 9 P.M., signal five or eight.

B. CHICH..GO farm etc. apply P.O. box 1476 indicates signal 4 or 7.

C. Beauty operator wanted etc. apply P.O. box 1476 indicates signal 5 or 8.

3. If the above listed signals and wireless messages cannot be made from Oahu, then on Maui Island, 6 miles to the northward of Kula Sanatorium at a point halfway between Lower Kula Road and Haleakala Road (latitude 20-40N, longitude 156-19W), visible from seaward to the southeast and southwest of Maui Island) the following signal bonfire will be made daily until your EXEX signal is received:

Time and Signal

- From 7-8: 3 or 6

- From 8-9: 4 or 7

- From 9-10: 5 or 8

(COMMENT: This message was sent on December 3, 1941 but was not translated by American cryptanalysts until after the attack on Pearl Harbor.)


USS Lexington Departs Hawaii

Noting that three battleships had been at sea for eight days, Consul Kita said that the vessels returned to port on Friday morning, December 5. On the same day, the Lexington and five heavy cruisers left port. In port on the afternoon of December 5 were eight battleships, three light cruisers, and sixteen destroyers, while four ships of the Honolulu class were in dock.

Consul Kita Notifies Tokyo of
Balloon Barrage Defenses

On December 2, 1941, Tokyo directed the Japanese Consul at Honolulu to wire day-by-day reports concerning observation balloons above Pearl Harbor, or any indication that they would be sent up. In view of the present situation, the presence of battleships, carriers, and cruisers was of utmost importance, Foreign Minister Togo declared. He asked also that he be advised whether or not the warships were provided with antimine (torpedo) nets. This dispatch was not translated until December 30, 1941.

In accordance with these orders, the Consul informed Tokyo on December 6 that 400 or 500 balloons had been ordered in America and that their use was being considered in the defense of Hawaii and Panama. He reported, however, that, as far as Hawaii was concerned, no mooring equipment had been set up at Pearl Harbor nor had the troops been selected to man them. Furthermore, there were no indications that any training for the maintenance of balloons was being undertaken.

In addition, it was difficult for him to imagine that the Hawaiian defenses actually possessed any balloons. Moreover, there were limits to the balloon defense of Pearl Harbor. He imagined that in all probability there was considerable opportunity left for a surprise attack against Pearl Harbor, Hickham, and Ford. He added that he thought the battleships did not have any torpedo nets, but he would investigate the details further.

Re the last part of your #123.

1. On the American continent in October the Army began training barrage balloons, but it is understood that they are considering the use of these balloons in the defense of Hawaii and Panama. Insofar as Hawaii is concerned, though investigations have been made in the neighborhood of Pearl Harbor, they have not set up mooring equipment, nor have they selected the troops to man them. Furthermore, there is no indication that any training for the maintenance of balloons is being undertaken. At the present time there are no signs of barrage balloon equipment. In addition, it is difficult to imagine that they have actually any. However, even though they have actually made preparations, because they must control the air over the water and land runways of the airports in the vicinity of Pearl Harbor, Hick, Ford and We, there are limits to the balloon defense of Pearl Harbor. I imagine that in all probability there is considerable opportunity left to take advantage for a surprise attack against these places.

2. In my opinion, the battleships do not have torpedo nets. The details are not known. I will report the results of my investigation.

 

Last Intercepted Intelligence Report Before Pearl Harbor Attack Lists Ships in Port

In an intercepted intelligence dispatch transmitted on December 6, 1941 from Hawaii, the last before the Japanese attack on Pearl Harbor, the Japanese Consul reported that a number of battleships and one submarine tender had entered port on the evening of December 5. Nine battleships, three light cruisers, three submarine tenders, and 17 destroyers were at anchor, and four light cruisers and two destroyers were lying at the docks. The heavy cruisers and airplane carriers had left Honolulu. It appeared that no air reconnaissance was being conducted by the fleet air arm.

(Comment: Berthed in Pearl Harbor were eight of the nine battleships of the US Pacific fleet, nine cruisers, and a third of the Fleet's destroyers. Battle Report, p 6.)

Inaccuracy of Japanese Intelligence Reports

Since it was obvious at this time that Japan was attempting to obtain a total picture of military and naval strength in the Philippines, we well as last- minute information of ship movements and troop allocations, the accuracy of their spy reports may be gauged by comparing the information with an estimate of the strength of US air forces in the Philippines on November 27, 1941, as released by the Office of the Chief of Naval Operations. Japanese agents estimated that 1,283 military and 26 naval planes were based in the Islands (the former was later very slightly raised). Since according to the American estimate, 43 Navy planes and 298 Army planes were based in the Philippine Islands, our air strength in the Islands was greatly overestimated: there were 17 more Navy planes then were reported but 985 fewer Army planes than were listed by Japanese agents.

Japanese Official Analyzes Roosevelt's
Domestic and Foreign Strategy

On November 12, 1941, a Japanese intelligence official in Washington sent Tokyo a report on the Roosevelt administration's method of dealing with the Japanese-American situation. In an effort to aid in the defeat of Germany, President Roosevelt had inaugurated military, economic, and industrial measures, which would eventually lead America into complete war. By assisting Great Britain, it had already entered the conflict on the high seas. While the US Army was not yet equipped to fight a war with Germany on land, for the present at least, the US Navy could engage German warships on the high seas. Nevertheless, in spite of the fact that President Roosevelt had almost dictatorial powers in regard to Congress and the military officials, the American people were not in complete sympathy with his policies. For example, on 10 November 1941, the Times Herald had stated that Roosevelt was as much a dictator as Hitler or Stalin. Furthermore, the American First Committee was secretly working to impeach President Roosevelt. On 30 October 1941 at Madison Square Garden, 8,000 members of the America First Committee gathered as a demonstration against the foreign policies of the present American Government.

In Washington, a former American Ambassador demanded that President Roosevelt be forced to resign his position as President by means of a referendum. He even went so far as to state that President Roosevelt might easily die during this disastrous period in the nation's history. This statement grew great applause from the audience. Apparently, the Japanese intelligence official went on to say, the move to impeach President Roosevelt was widespread and was initiated by many varying factions. An editorial in the Times Herald on November 4, 1941 warned that it would be impossible for Congress to impeach President Roosevelt because of the whip he held over the Army and Navy. Nevertheless, the editorial in this and other papers did mention the possibility of President Roosevelt's being impeached at some time, and the Japanese intelligence official believed this to be extremely significant.

As an indication that the American people were not entirely behind President Roosevelt's aid to Britain, the Japanese official cited the occurrence in Detroit when Ambassador Halifax was pelted with eggs. The American public as a whole had begun to view the prospect of war in its unprecedented aspects and after the sinking of the Reuben James, the country received a great shock. Although President Roosevelt took advantage of this sinking to declare an unlimited national emergency, in his speech on October 27, 1942, he did not stress foreign questions but placed his emphasis almost entirely upon America's internal problems.

From the Intelligence Official.

1. The ROOSEVELT administration is dashing along the road of military, economic, and industrial reconstruction with the object of defeating the Nazis.

So far as war on the sea is concerned, the United States has already entered the conflict. Even if ROOSEVELT should now decide to leave the Nazis be, he is already in too deep. Even though he tried to do a 180 degree turn, his economic reconstructionists would not let him. Therefore, it can be said that the United States is following the one road to complete war.

2. It is true that the American army is not yet equipped, but even if war were declared against Germany, no more than the present ocean fighting would be necessary and, therefore, such a declaration is possible. The reason why things are not going so well for the administration in this connection, however, is because the people are not complete behind it.

ROOSEVELT has the full support of the government, the military, and the Congress and is tantamount to a dictator (on the 10th, the Times Herald said in an editorial that ROOSEVELT is a dictator in no way less than HITLER or STALIN). The people, however, most certainly do not support ROOSEVELT. During the last two or three weeks this has been particularly evident. Let us look into some concrete examples: According to reliable reports the leaders of the America First Committee are secretly endeavoring with all their ingenuity to impeach ROOSEVELT. The stronger government pressure against it becomes, the more belligerent does this committee grow, and it may well be that the time will come when they will resort to force. The pressure of the government against the America First Committee is also becoming fierce. On October 30 in New York, there was a meeting of this committee, but they could not make any radio broadcasts. ROOSEVELT's own life is in grave danger. On that night in Madison Square Garden, the immense crowd totally 8,000 filled the building to overflowing.

At a mass meeting in Washington, _ _ _ _, a former Ambassador, made a scathing attack on the ROOSEVELT regime and demanded a referendum against this deliberate drift toward war. On that occasion he said that at this so fateful moment in the nation's history Roosevelt might die. These were words of profound meaning and drew great applause from the audience. The Times Herald in an editorial said that the President holds the whip over the Army and Navy and has the full support of the Government. Therefore, it will be impossible for the Congress to impeach him. The editorial said, however, that some believe that he will be impeached, in any case, later on. Now, for papers in their editorials to use the world "impeach" cannot be overlooked as something light. Furthermore, pickets in front of the White House recently carried placards on which were written the words "Impeach the President". Another thing, some days ago in Detroit, Ambassador HALIFAX was pelted with eggs. Again the sinking of the Reuben James gave the popular spirit of this country a great shock and filled the people with a gloomy foreboding. In his speech on October 27th, ROOSEVELT did not stress foreign questions so much as he did internal matters. This is to be regarded as a declaration of internal warfare whereby ROOSEVELT whipped from its scabbard the sword of an unlimited national emergency.

2. The congress, as I said, is supporting ROOSEVELT. True enough, the Senate approved the entrance of armed merchantmen into the war zones; however, the actual figures were 50 to 37, and this could not, by any means, be called a crushing defeat of the opponents. This also may be regarded as a reflection of public opinion.

Things being as they are in he country, in order to dispel the dilemma and to condition the people for a war against Germany, it may be now that a counter-hand will be played. I mean to say, many people in the United States fear the German war machine frightfully. However, they know how we have fought so hard in China for four years and figure that we are about worn out. They also figure that we are weak in materials. They do not think that we could resist them very much and optimize over how quick we could be to come to our knees.

If we scrutinize this psychology closely, we find that the ROOSEVELT administration, although it does not want a two-ocean war, would probably not do anything to prevent the outbreak of a war with Japan, depending on how we Japanese act. Perhaps a point-blank declaration of war might be made. Then the people's thirst for blood could be stimulated, an unlimited emergency declared, the America First Committee dispersed, and all opposition crushed. Then they figure the popular mind might turn favorable for a war with Germany. In other words, we Japanese would be merely the tool with which the American administration prepares the way for coming to grips with the Reich.

4. What will happen if the United States and Japan come to blows? Well, Germany now has a vast occupied territory and is in the most favorable position to talk peace. England is already complaining that the United States is not sending her enough help. Germany, of course, does not want a long war, and she may suddenly, on unexpectedly generous terms, conclude peace with England. I mean to say that while the United States would be at grips with us, American aid to England would naturally slow down and give Germany a chance to make a separate peace with Great Britain. Germany will certainly do her best to achieve this feat.

(Part 4 of 4.)

The New Deal failed, and the opposition to ROOSEVELT within the country became unmanageable. Just then the European war took a more lively turn through Germany's invasion of the Netherlands. ROOSEVELT, who is well-versed in international questions, joined the war then and there. It might be said that HITLER's attack on the Netherlands caused ROOSEVELT to enter the struggle immediately. Japanese-American relations are now at identically that same pass. I mean to say that a war with Japan would put the people squarely behind ROOSEVELT and make him a dictator. He knows fully that if he has to fight, there will be a suitable opportunity which would not admit delaying war. Furthermore, in view of Japan's foreign policy, it can be seen that our relations with the United States have reached such a pass that a decision on war is about the only thing that could raise them from the dead. Judging from internal conditions in the United States, for the foregoing reasons there is no hope for a thorough-going pact at the present time. It would be better to devise some relatively easy small-scale makeshift of a temporary nature laying stress on economic matters. Germany will keep sinking American ships and the President's position will become harder and harder, so as soon as a show-down with Germany is inevitable, then we can get a full-fledged pact. Again, if we do have to fight the United States, we could do this much better after she is at war with Germany.
