Mexico stole it from Spain who stole it from the Aztecs and other native peoples.
Mexico stole (what is now southwestern United States) from the American Indian. Dunno who they stole it from but they sure stole portions of it from rival Indian tribes.
I believe Mexico only had it for about 20 years it was deserted basically a few people and american indians..wasn’t worth 15 million back then...but we paid them.nuff said our leaders have abdicated and ignored their responsibilities for decades to get votes and allowed this crap to fester and now it is boiling over.its like the overspending it will have a day of reckoning also...politicians in congress for forty plus years...ridiculous and needs to change. look at doge and all the waste fraud and abuse....sickening. maybe we are at the cusp of a civil war..we the people against corrupt politicians?
you forgot the french had mexico too
