They won't come also if the borders are closed against them

Stop the kemahuan is not responsibility of US. It's the origin country responsibility, not from US. Unless you're advocating US to invade south america and take over their country?

Nope. They can close the borders. Whatever kemahuan oso useless if borders closed. That's the idea

Dude, whats with arguing off tangent liddat? Did I say anything about caging USA bar anything including animals, snakes, insects from crawling into USA? Common sense a bit la when ppl say close borders basically means dun allow illegal immigrants to come in. You interpret that literally until snakes n insects for wat?

I have to say "close the border as in deploy lots of guards at the border, do not allow illegal immigrants to sneak in, but not exactly solid wall not the kind from east to west that even snakes and insects oso cannot cross, can be wired mesh or something, as long as sufficient to block illegal immigrants to cross over with exception of legal personnel or animals or flora and fauna?" liddat baru understand ka?
