Hi Mrkim,

With all due respect to your opinion, I would like to invite you to read more about History of the US and Mexico, it helps to read both sides of the story to reach a balanced understanding.
I learned that years ago when after watching "The Alamo" with John Wayne (in the 70s I think) and visiting The Alamo in San Antonio Texas (in the 80s) that I learned that bad history/movies and real life don't always agree, if you are one of the lucky ones that watched History Channel's Alamo you might see the other side of the story and my meaning.
It might surprise you but when the US invaded Mexico with the plan to take half the country it wasn't planned by a US General or President, It was planned and directed by somebody in Mexico City... Yes the invasion was planned by the Generalisimo president of Mexico Antonio de Santa Ana! (for $30 million reasons and he was the same guy from El Alamo).
And if you look carefully there are books written about that episode of Mexican history. Something else you probably dont know is that during the dictatorship of General Porfirio Diaz, the US planned to invade and take the rest of the country (I think it was around 1895) but Porfirio Diaz was a smart politician and found a way to stop said takeover.
