Great!!!!! Don't squeal when Mexico takes it back.
LOL...
When the South American kidnapping gangs and Cartels get word that Texas is no longer under the protection of the United States, every Texas cheerleader and trophy wife will be turned out into the streets as fast as you can say "The stars at night, are big and bright..."
Texas will become like Dodge City, Deadwood, and Tombstone circa 1870s.
We'd have to build a wall around Austin, because they're not really Texas.
Uhhh. What?
You'll(I'd say we'll, but I'd fucking leave before the war starts) be dealing with cartels looking to expand their border access to the United States. And then you wouldn't have all those federal funds to secure the border.
Would be no match for the Cartels looking to expand and open up new avenues.
The boarder protection will by tiny when they realize that they buy power from out of state.
Any U.S. Corp with home offices in Texas will leave the state.
The incredible domino chain of collapsing local economies, loss of basic services....
