Texas reserves the right to secede. It was part of the agreement made when Texas entered the Union. Many people interpret that agreement as not binding but it is. The documents are in Austin at the Capitol Library. Other states have no language as such. Texas also demanded and received all air space, mineral rights, water rights, and land. That’s why there is almost no BLM (Bureau of Land Management) land in the state. No other state enjoys that latitude. When you go to google to find out whether Texas can secede all you are going to get is ‘no’ even by pundits in Texas but those pundits are simply government boot licking ass clowns. If push comes to shove (and it’s gotta be a massive shove) Texas can and will bail.
