If history could be changed... If Sam Houston killed Santa Anna after capturing him and moved his army down south to take over Mexico and annexed it into Texas (which would later become part of the U.S.), all the way down to Panama or even just to Costa-Rica ... just imagine how different things would be.
No illegal immigration problems, different mindset of the people, drug trade would have a much harder time because of a smaller border to protect/watch over, etc, etc.
But history is what it is... question is what is to be future history?
Stolen land? It was acquired during an act of war... war against Mexico, they lost and were driven back and SOLD their northern territories to the U.S.

If they want it back then they can petition an act of war against the U.S. and lose again... at a great cost of life... theirs. Or take all that drug money and buy it back... at present value. Provided that it IS for sale.
Personally I got nothing against Mexicans per se' except those who are in this country and trying to find a better life but are breaking our laws. If they're in this country and just trying to find a better life and are keeping to themselves while awaiting citizenship then fine as long as the application is in.
Predominate language here is English look at the signs all around and nearly everything that you read is printed in English from soup labels to the delivery trucks that bring them to the stores. I'm guessing that 90% of the books in an average public library is in English. So learn it if you want to live here. It'll make navigating the streets a lot easier when you can read the street signs.
As for the kids that treat the classroom and teachers with disdain, kick 'em out... don't waste my tax dollars on something that isn't wanted or appreciated, the education that is being provided though they're illegally in this country but tolerated.
I agree... don't like it GTFO and make your own country a better place before trying to improve mine.
