I have to say I completely disagree with you, on this one.
The US was approached by Churchill in May 1940. The Lend-Lease program was signed into law in March 1941.
Stalin entered our program in 1941 and we sent materials before August 1941 to the USSR.
The USSR was already fighting against German, then. The fight against the Nazis needed all side to fight, unless you wanted even more US citizens dead, as Russia was conquered by Germany.
Churchill did nothing to help the USSR be “saved,” and Churchill was one of the most stellar leaders of the last century.
You need to bone up on your history.
Churchhill was in competition with Stalin to get aid from the USA
