Yes, we bought all the SW Territory and California from Mexico in 3 separate transactions.

We bought the midwest part of our country from North to South from France with the Louisiana Purchase transaction!

Nothing unusual at all about how we acquired the lands from Mexico.

They're just whiners who don't want to honor a deal, they always want to present themselves as some victim. They're beggars really, whiners truly and untrustworthy. Not a good neighbor at all. When you want to threaten not cooperating with the US on counter-terrorism so you can keep running illegal drugs and illegal aliens into the US, then you are no one's friend, you're SCUM.
