Biden and Trump are both dimwits, but different types. Biden is like the H.S. Jock who is manipulated by the town's rich family. Trump is the class clown, also manipulated. All Presidents are figureheads, though some more thoughtful than others.
So my criticisms of Biden, even if true, aren't ultimately important. What's worse about him, and I predicted this (one of the very, very few thing correctly) is that Trump's personal narcissism cock-blocks military adventures. He simply doesn't want any general taking the stage in front of him.
Biden loves to stand behind generals and play defender of the free world. That's what he's been doing to horrible effect. Again, not because of him, but because those forces have freer reign than they had under Trump.
If Trump is elected, he'd be no better. He can't put these wars back in the bottle.
No matter who is elected I'll make one prediction for you. America will start carpet bombing the bejesus out of someone soon. The Israelis are just the beginning of that. Biden has made sure the Chinese will be as less motivated to just stand aside as is their usual.
