On April 12 1945, FDR was in Hot Springs Georiga (with his mistress, all the good ones had mistresses, but I digress) having a portrait done when all of a sudden he dropped dead due to deficit spending a brain aneryuesm.

Things we know:

Stalin was a bastard
FDR was charming
Truman was gutless and to make matters worse he overcompensated by posturing.

FDR and Stalin had struck up a "friendshp" (term used loosely, like a nickel hooker when paris island is on a weekend pass)

Had FDR lived could the west have gotten more concessions in the post WWII world?
