FDR was a Socialist - heart and soul.
His only concern in life was being reelected every four years.
He was not naive, and he did not blunder away anything.
Everything that FDR did at Yalta was deliberate.
Everything Dementia Joe does is also deliberate.
A country of over 300 million people and the few hundred in Congress, one in the WH, and 50 in state houses as well as all the state legislatures have to be the most stupid .01% in the country. Amazing we can't do any better.
