of course the u.s. can migrate anywhere and take whatever it wants. try and stop the u.s. war, sanctions, coups, theft of resources, if migrants seeking asylum from environmental collapse, war, sanctions, or coups by the u.s. manage to make their way here they will find torture and incarceration. the u.s. aim's to rule the world. i think the only possibility for a shift is a global revolution of the poor. but the rulers have an arsenal that can annihilate the earth in a heartbeat. either way, people are dying.
