You guys talk about Biden like he's running the show. You've seen him lately, right?
Is the guy a doddering old fool or a dangerous demagogue? It can’t be both simultaneously
The simple solution to the contradiction you propose is: He is a doddering old fool, who is controlled by dangerous demagogues. (And actually, this might describe his predecessor as well.)
But that doesn't mean we can't appreciate when they occasionally do something good (regardless of their motivations), and this is one of those times.
There’s no drug in the world that makes someone go from doddering to able to give long speeches and stay on point.
