The 1/6 Capitol breach would not have happened, if Donald Trump had not instilled his followers with the false hope that he could still retain the presidency ... and worse, also convinced them that they could collectively help him do it.
While Donald Trump did not instruct the crowd in front of The White House to forcibly enter the Capitol, he did instruct them to march down there. If he didn't understand what that would lead to? He should have ... but I think he did know what it would lead to, and a riot is exactly what he wanted.
Being the ego-maniac that he is, I think Trump was flattered by the riot, and his "We have to have peace. So go home. We love you. You're very special," video message reflects that. He certainly wasn't angry at those Capitol rioters, was he? He was flattered by how much they cared, and what they were willing to do for him. That is who Trump is.
