I’m sure you have great intentions in your thinking but it is wildly unreasonable.
Israelis generally want to live in an Israeli-run Israel, and Ukrainians generally want to live in a Ukrainian-run Ukraine.
Why would they move to the US and lose their national identity?
(This is a very loose analogy; don't read too much into it)
History has shown quiet clearly that Imperialistic Ambitions never stop until they are stopped. The way to end the War in Ukraine is to help them win. Unfortunately there will never be an end to the war in the M.E.
Just my opinion.
Some religious leaders argue for global citizenship.

- 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.
