In my history classes, I learned that the Mexicans got their asses kicked every time they went up against the Americans. Don’t tell me they are stupid enough to try it again.
What’s really funny is that the Spanish who laid claim to California, could not resupply their missions in California overland, they has to do it by sea, because they could not get past the Apaches and Commanches.
Mexicans have no valid claim to California.
Remember the Alamo? Mexico got a cheap shot in! Mexico has been sending people across the border to do just this because they feel that most of the Southern USA belongs to them. If CA does secede from the Union, then Mexico will have accomplished some of their goal and the NOI of will take notice. As they too want a parcel of the most fertile lands in the USA as their own black owned country.
