Yes, we took those states from Mexico, as the Mexicans took their land from Spain before that, and Spain took land from the Aztecs and Maya before that, and the Aztecs took land from the Toltecs, and the Maya took land from the Olmecs and Zapotecs before that, and on and on and on. This has been the way of mankind from the beginning. Tell you friend,”Yes, it’s true. Too bad, get over it.”
Don’t forget France. They managed to rule part of Mexico for a while as did the Dutch if I remember correctly.
