No, the Texas war for Independence wasn't at all like that. The Mexicans couldn't hold the northern territories against Indian raiders (Comanche and others), so the Mexicans invited Anglo settlers into the area to help secure the area. It worked. The lands were becoming secure against raids, but then the dictator Santa Ana violated the terms of settlement. The new landowners said no to his demands, and the war was on. Mexico got its ass kicked, and that's that.

Later, in the 1840's, blond haired blue eyed Emperor Maximillian of Mexico made some noises about invading the US, then Mexico sided with the Germans in WW1 and did some border raids, then they sympathized with the Nazis in WW2 but weren't in a position to bother the US. Mexicans need to get away from their strongman rule mentality, then maybe they can make the country a decent place to live.

But Mexico is just a bit of the problem. The Mexican border is a major issue, but many (used to be a majority) of the people coming across that border illegally are European, Asian, Central & South American, etc. A Swiss man I work with came into the US over 10 years ago, and we're still trying to explain the concept of income tax to him. He had a 10-year free ride on paying income tax in the US, same as all other immigrants. That's in the new amnAsty bill, too--a tax moratorium. So this talk about what immigrants "pay in" to the system is a lie. The whole bill is a lie. The Senate was talking about censuring Sen. Sessions of Alabama for making the bill public (remember the article about the '20 loopholes'). The Democrat/Republican criminals are hoping to pass this IN SECRET, it's so bad.
