FDR probably made the right choice at the time, Defeating the Nazi’s had to be first priority, the lack of action after the war, when it was blindingly obvious what had happened however, is inexcusable.
I still don’t get it. Why would exposing Katyn hurt the fight against the Nazis? There’s just no way Stalin would make a seperate peace. That leaves Churchill and FDR’s delusions of sweet talking Russia into doing their bidding, which was ridiculous. Then there was the Pacific, which does lend an excuse, and the only excuse.
