Mexico is kind of doing that now. But I get your point.
I don’t think Mexico is arming people on our side of the border, but I do think they are seeking to reclaim massive portions of United States territory. This is a movement to overpopulate regions of the United States with foreign nationals to the point that they want their own government, and not to be a part of the U. S. any longer.
And for all the talk of these people becoming Americanized, it’s just not happening. There are regions inside our nation now that are more like Mexico than the U. S.
Millions of acres of cleared land wound up in U. S. hands in 1852. Today after 160 years, these lands are no longer vacant. Trillions of dollars of improvements have been made. Now Mexico wants it back, so it can capitalize on what it would gain if it were chosen to be the new government.
If an entity like the imagined Aztlan were to come into being, Mexico would still not have the dominant neighbor to it’s north that it does now.
This is open Mexican aggression.
