>>1848 was when the U.S. defeated Mexico for that sliver of land that we PURCHASED legally.
I’ve never heard California, Nevada, Utah, Colorado, New Mexico, Arizona, and parts of Wyoming defined as a ‘sliver of land’. These are some the largest states in the country, after Alaska and Texas.
Are you thinking of the Gadsden Purchase? That is a pretty small parcel (relatively).
What I find hilarious is that this land they claim as theirs was only part of the Mexican state from ~1821-1848. A mere 27 years. I have cars older than that.
....and I have a carton of sour cream in my refrigerator older than that.
