How did Trump end up where he is? This documentary may be helpful: https://tubitv.com/movies/100020971/bad-faith

TL; DW: he's been recruited as an instrument in the long game of the USA white nationalist subculture. Their aim is not to take over the existing government, but to destroy it and replace it with a theocracy. He's the destroyer. Gilead, here we come...

As to false flag, unlikely, and if so it was not Trump's plan or script, he would never choose to be seen diving to the floor and pig-piled by security bros. And if you slow-mo or frame-by-frame the original news-cam video, look at his face whenever it's visible after the shot. He's a performer, but he's no actor. He couldn't fake that expression of regressed pure terror for a second, never mind all the way to the SUV. Even as his performative habits/reflexes kick in, with the fist-pumping and mouthing "fight," his face still says shock and terror. Likewise in the pic someone got of his face in profile while still down on the stage.
