It's pretty clear that Biden isn't there mentally. Even if he was, he's been wrong about every public policy for 50 years. I'd link to the video of his racist speech in favor of the 1994 crime bill, but Youtube censored it. There's palace intrigue galore going on, which even if the media was curious about, which they're not, they wouldn't report anyway because it would reflect negatively on Biden. He's being controlled by his advisors, and he constantly says things he obviously heard in meetings but wasn't supposed to say in public. Like "we will militarily defend Taiwan" even though there is no such treaty and strategic ambiguity has been a cornerstone of US policy since the 50s. Then the White House immediately contradicts him and instructs the press to bleat that the president didn't really mean what he said, despite him clearly saying it. It's a poorly coordinated shitshow, with people fighting in the shadows.
