President Theodore Roosevelt summed up his foreign policy as "Speak Softly and Carry a Big Stick," meaning the U.S. would try diplomacy first, but failing that we would when necessary use force to carry forth our interests overseas.
President Franklin Delano Roosevelt's foreign policy was to try to stay out of foreign affairs that might lead to war, but the U. S. felt it would be to the detriment of the U.S. eventually if Germany should defeat Britain and thus control Europe, so he came up with the Lend/Lease program to supply Britain with materials of war. Eventually the U.S. entered the war on the side of Great Britain and the other Allies.
