Sorry, but that's a cop out. Nothing "blinded" Biden. He saw it all and was unfazed enough to let it play out, and also lie about seeing photos of things that framed Hamas for atrocities it didn't commit.
As for the former Obama aides speaking out only now. I think they're the people referred to in the title of the book One Day, Everyone Will Have Always Been Against This by Omar El Akkad.
