Thats not how timelines work. Every single move you do, creates an infinite amounts of universes, like imagine you dragging a mouse on the screen quickly and there are small mini-copies chasing the cursor and copying its movement. Pretty much, you the one that took a sip of a coffee, and you the one that didnt take a sip of a coffee, both are different people in different universes that created a wave of billion new universes.

You cannot just collectively change the universes for the entire planet unless you have some kind of technology to do that, and i assume if THEY had that technology, trump wouldnt even be a problem, they would change the timeline into where the planet is in full control of THEM and trump cant do shit.
