FDR was a great man but he was forged in the fires of a time far far worse. I shudder to think how bad things need to get before we get leadership like that back.
Ok, full props to Zelenskyy. He is certainly doing a better job than any current leaders I can think of and he should have been able to count on the U.S. for full support. I would even support deploying our own troops.
But better than any leader the U.S. has had for 100 years? That's quite the suck up. You can respect and support without being a blatant kiss ass. It's embarrassing for you and for him.
He served five terms because he was so good he was massively popular, the conservatives paniced and pushed for term limits afterwards as they were scared of the idea of people running with policies that benifted the majority of people repetedly getting long periods of power like that.
