You draw tenuous parallels at best. My parents chose to come here and I consider Australia my home. I can return to Great Britain whenever I desire.
Let me approach this from a different perspective, I'm sure the fantasy will appeal to you.
Let's say that tomorrow some all powerful extraterrestrial organisation decided that the United States was to be shared with Africans, who arrive in their millions against your will and are gifted substantial amounts of your land on the pretext it was to be equally shared in harmony.
If they then decide they want it all, and over the years they take it away from you and your countrymen piece by piece, while they murder and abuse whoever they please.
Let's also assume that fighting them is not possible as they are stronger then you, and of course they are supported by aliens from another galaxy with far more advanced weaponry. They also possess the ability to make your own weapons useless, so any chance of defeating these fine upstanding chosen ones is impossible.
You'd just leave and try to live in a land, far, far away? You wouldn't simply flee to Mexico or Canada if this was a safe haven? Let's also assume that Rump has built a special wall that makes Mexico and Canada somewhat immune to these aliens special powers.
Underage, trafficked prostitutes hey?
Pardon me, I didn't realize you had such a complete grasp on what the UN is all about. *sarcastic smile*
I hear Norway is nice.
Live long and prosper.
