Yep, and it's Sam Houston's fault. He should have executed Santa Ana, his army, and taken all of Mexico.
Had he done so, the Panama Canal would be in Texas, where it belongs, and there would be no such thing as a Mexican.
Well considering the odds, they did pretty D well if you ask me. Pershing should have taken full control and declared it an new American territory while he was there.
