He's a bully, and this is the way he always operates. He's not going to invade Greenland or Panama or Canada; he just wants to force their leaders to capitulate in some way so as to remind them of his power. And renaming the Gulf of Mexico, which wouldn't actually benefit the US in any way, is just a performance for his MAGA base, like promising to build the border wall that never got built. MAGA didn't even care that the wall never got built; they just liked it that he talked about it. Bleach-blond bad body MAGA hag MTG is loving it.

Trump has 60-90 days to get his war on, before he has to have permission from Congress.

Trump wants to be a dictator, and he thinks he can act like Putin and expand the American Empire onto our allies.

It won't go over well with the American Public...
