A good start would be to block money transfers to Mexico, and to effectively seal the borders. What a novel idea.
Good point. Tax wire transfers to Mexico made by those lacking proof of legal presence in the U.S. Spend the money on deportations.
After V-E Day, the army somehow managed to bring home hundreds of thousands of GIs in a fairly short period, peaking at just over 400k during Sept ‘44. Our population then was less than half what it is now.
I said it before; charge Mexico $2,000/mo for every illegal. And watch the Mexican Federales protect the border for us.
