The problem with option A is that you can’t force countries to simply take deported people, even their own citizens. That’s why they need the military, to set up option B.
The Nazis did the same thing saying the camps were only a holding pen while the people were being deported. But when they couldn’t deport enough of them and the camps were getting full, well, they thought of a “final solution”.
And I highly doubt they’ll be doing anything more than
A) shoving people over the southern border to Mexico (regardless of ancestry/origin) and shooting at you if you try to return
Or
B) Concentration camps.

You can force other countries to do whatever you want when you have no scruples and the world’s largest military.
