The second Donald Trump threatened to invade a nation allied with France is the second anyone who works with Trump became a legitimate military target.
Like a cruel child dismembering a spider one limb at a time France and other nations around the world will meticulously destroy whatever resources people like Musk have and the influence it gives him over their countries.
If Musk displays a sufficient level of resistance to these actions the French will simply assassinate him.
PS Yes, Greenpeace is a bunch of scientifically-illiterate fools who have caused far more damage than they prevented. Doesn't matter because what France did was still clearly against the law.
