International cooperation on which enduring peace must be based is not a one-way street. Nations like individuals do not always see alike or think alike, and international cooperation and progress are not helped by any Nation assuming that it has a monopoly of wisdom or of virtue.



Perfectionism, no less than isolationism or imperialism or power politics, may obstruct the paths to international peace. Let us not forget that the retreat to isolationism a quarter of a century ago was started not by a direct attack against international cooperation but against the alleged imperfections of the peace.



In our disillusionment after the last war we preferred international anarchy to international cooperation with Nations which did not see and think exactly as we did. We gave up the hope of gradually achieving a better peace because we had not the courage to fulfill our responsibilities in an admittedly imperfect world.



We support the greatest possible freedom of trade and commerce.



We Americans have always believed in freedom of opportunity, and equality of opportunity remains one of the principal objectives of our national life. What we believe in for individuals, we believe in also for Nations. We are opposed to restrictions, whether by public act or private arrangement, which distort and impair commerce, transit, and trade.



We have house-cleaning of our own to do in this regard. But it is our hope, not only in the interest of our own prosperity but in the interest of the prosperity of the world, that trade and commerce and access to materials and markets may be freer after this war than ever before in the history of the world.

Trump sounds like the master of the "one way street". But then he is not a big fan of international cooperation either. He will tell Mexico what is going to happen. He will tell China what is going to happen. He will tell Muslims what is going to happen.



FDR he ain't. FDR may not have supported the TPP. (He had his own International Trade Organization that might have made TPP irrelevant anyway.) Who knows. But his did support the "greatest possible freedom of trade and commerce", not the "least possible trade and commerce".
