No, I believe he was correct in saying the Russkies cannot be trusted (and he was blasted in the press and IKe for saying so), but at that point, he was correct in the mindset. We just didnt have the manpower with the fighting in the Pacific.
That is one serious screw loose to ask US soldiers in May of 1945 to get ready for Barbarossa II, along with rearmed nazis. There was already a lot of bitterness at the idea of them being sent to the Pacific to invade Japan.
That would have been fun to sell to the American public who all saw the easter front meatgrinder since 1941. And for what? To keep Germany safe?
Utterly insane. Patton was a good general, but like most good Generals, he also had a serious personal screw loose and should never SET national policy.
