I content that this may very well be true since Mexicans can just walk here instead of having to be transported by ships. A quick read of history reveals that more (far more) nations have perrished due to invasion by immirgrants then by armies. Also a small deicated elite can control the actions of a far greater number so if only 5 or 10 percent of the Mexicans living here wanted Asland? Then they could get most of the others to go along.
