President Roosevelt to the Ambassador in Japan (Grew)15

Dear Joe: I have given careful consideration to your letter of December 14.16

First, I want to say how helpful it is to have your over-all estimates and reflections—based as they are upon a rare combination of first-hand observation, long experience with our Japanese relations, and masterly judgment. I find myself in decided agreement with your conclusions.

I also want you to know how much I appreciate your kind words of congratulation on my re-election and your expression of confidence in my conduct of our foreign affairs.

As to your very natural request for an indication of my views as to certain aspects of our future attitude toward developments in the Far East, I believe that the fundamental proposition is that we must recognize that the hostilities in Europe, in Africa, and in Asia are all parts of a single world conflict. We must, consequently, recognize that our interests are menaced both in Europe and in the Far East. We are engaged in the task of defending our way of life and our vital national interests wherever they are seriously endangered. Our strategy of self-defense must be a global strategy which takes account of every front and takes advantage of every opportunity to contribute to our total security.

You suggest as one of the chief factors in the problem of our attitude toward Japan the question whether our getting into war with Japan would so handicap our help to Britain in Europe as to make the difference to Britain between victory and defeat. In this connection it seems to me that we must consider whether, if Japan should gain possession of the region of the Netherlands East Indies and the Malay Peninsula, the chances of England’s winning in her struggle with Germany would not be decreased thereby. The British Isles, the British in those Isles, have been able to exist and to defend themselves not only because they have prepared strong local defenses but also because as the heart and the nerve center of the British Empire they have been able to draw upon vast resources for their sustenance and to bring into operation against their enemies economic, military and naval pressures on a world-wide scale. They live by importing goods from all parts of the world and by utilizing large overseas financial resources. They are defended not only by measures of defense carried out locally but also by distant and widespread economic, military, and naval activities which both contribute to the maintenance of their supplies, deny certain sources of supply to their enemies, and prevent those enemies from concentrating the full force of their armed power against the heart and the nerve center of the Empire. The British need assistance along the lines of our generally established policies at many points, assistance which in the case of the Far East is certainly well within the realm of “possibility” so far as the capacity of the United States is concerned. Their defense strategy must in the nature of things be global. Our strategy of giving them assistance toward ensuring our own security must envisage both sending of supplies to England and helping to prevent a closing of channels of communication to and from various parts of the world, so that other important sources of supply will not be denied to the British and be added to the assets of the other side.

You also suggest as chief factors in the problem the questions whether and when Britain is likely to win the European war. As I have indicated above, the conflict is world-wide, not merely a European [Page 8] war. I firmly believe, as I have recently declared publicly, that the British, with our help, will be victorious in this conflict. The conflict may well be long and we must bear in mind that when England is victorious she may not have left the strength that would be needed to bring about a rearrangement of such territorial changes in the western and southern Pacific as might occur during the course of the conflict if Japan is not kept within bounds. I judge from the remarks which appear at the bottom of page 4 and at the top of page 5 of your letter that you, too, attach due importance to this aspect of the problem.

I am giving you my thoughts at this length because the problems which we face are so vast and so interrelated that any attempt even to state them compels one to think in terms of five continents and seven seas. In conclusion, I must emphasize that, our problem being one of defense, we can not lay down hard and fast plans. As each new development occurs we must, in the light of the circumstances then existing, decide when and where and how we can most effectively marshal and make use of our resources.

With warmest regards,

[
Franklin D. Roosevelt
