When World War II started, America was isolationist and the Soviet Union collaborationist.
The U.S. may have been "isolationist" in terms of formal declarations of war, but there's no question that we were already involved in the war in terms of supplying one side and providing direct military support. I find it hard to take an author seriously when he describes America as "isolationist" before World War II when it was American-made ships carrying American supplies, escorted by American submarines, that kept Great Britain in the game before 1941.
VDH is correct in saying that America was icolationist ‘when WW2 started’. Yes, America supplied both Britain and later Russia with equipment after Lend-Lease was passed, but Britain had to endure a long year or so before Congress passed Lend-Lease. The supplies from America before then were pretty paltry and often consisted of obsolete equipment. FDR had to proceed slowly in helping Britain because Americans did not want to join the war.
not only was America isolationist then it still is now.
Many isolationists are alive and well and posting on Free Republic
The war started in 1939, not 1941, and definitely in ‘39 America was isolationist.
