So what said the government. We were buddies with the murdering "Uncle Joe" Stalin under FDR, and then we took under our wing, the minions of Little Ade Hitler, Uncle Joe's former bosom buddy, in our new struggle against the Commies.
We were "shocked, shocked" to discover that Uncle Joe was trying to give us a royal screwing after the war, and we needed all the help we could get.
I guess national interest calls for odious decisions. In any event both Hitler and Stalin killed millions. Some choice.
