Here is Joe Biden in 1997 saying that "the one thing" that could provoke a "vigorous and hostile" Russian response would be if NATO expanded to the Baltic states. 

How right he was.

Compare how he was 27 years ago when he was in his prime, aged 55, with how he is now.

He was impressive then, though never good enough to be president. That is why he never came better than fourth in a primary until he won South Carolina in 2020, when President Obama and the Democrat grandees intervened to arrange that he beat Bernie Saunders.
