Tenth Amendment Powers of States and people: The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.
As stated many times by the founders, Secession is a State power and they spoke many times about its proper use in protecting the state.
Since you have decided to go beyond the Constitution, can a state be expelled? Can half of a state decide to secede from a state? Can a state decide to secede and decide that they would like to be annexed by another nation- can South Florida decide that they would like to seced from Florida and the US and decide to become a part of Cuba. Can a foreeable Latin majority in Mexico decide to hold a vote and decide that Texas is now a state of Mexico? Can Saudi Arabia annex Detroit’s large muslim population if they hold a vote and agree to it?
None of these are in the Constitution, any of these example covered by the 10th Amendment?
