In what world would this work? - people want to live in their ancestral homelands, in their own houses - lots of Americans would get pissed off, causing hostility towards the new arrivals and those that put them there - integrating tens of millions of people in a short time period would be a crazy challenge - people would decide that they don't want to move, and that they want to stay and fight. Do you deny them that right? Do you take them away by force, for those that wanted to stay? - the newly moved governments would no longer be sovereign (and if they were made sovereign by the host government donating them some land they can rule over, that would piss off the anti-immigrant brigade off even more) Those are just the logistical challenges. And there's a lot more.
