The ties that bind.
You don't seem to understand the dynamics of nationalism. Mexico is their home, we are only a cow to slaughter and feed them and their families. The Huns who raided and pillaged the Roman Empire were only looking to feed their families as well, but they brought a civilization to its knees in the process.
There is no difference between the Hun and the Mexican. They are both invaders looking to steal from a wealthy and "over civilized" victim. This is more akin to a mugging than anything else. Shades of Albania and Kosovo on a grand scale.
