Best to go ahead and set up 700 miles of concertina wire along our southern border.
Just today, the Mexican government, and this is a very important step, requested the intervention of the U.N.,..
I said this is what Mexico would do in seizing a opportunity to generate $$$$ from the UN.......like Turkey they will then establish a refugee camp ....and then use them as ‘political cannon fodder’ ....leverage to negotiate with the US to get what they want or threaten to cut them loose on the USA.
