I think we’re not talking about the same thing. Individual acts of terrorism are not significant in my view, the US gets a bunch of politically motivated shootings every year and it accomplishes absolutely nothing. They are horrible tragedies, but not political drivers.
I’m not Nostradamus but my guess is that if Trump were to suddenly up and die, his movement would fizzle out pretty quickly. His lackeys would fight for power Game of Thrones style, which would fragment the movement and make it essentially toothless. His fans would be agitated for a while, most wouldn’t do shit about it, a few would attempt shootings, even fewer would succeed and make headlines for a couple days. But nothing politically significant would happen. Just my $0.02 !
