The Framers included both Article IV, § 4, which promises that the federal government “shall protect each [State] against invasion,” and Article I, § 10, Clause 3, which acknowledges “the States' sovereign interest in protecting their borders.”
Barbwire is set up at the border to cause damage. It is actually even worse than not having it, since border agents are required to seek medical assistance for any individual hurt during an operation.
Section 10 Powers Denied States
Clause 3 Acts Requiring Consent of Congress
No State shall, without the Consent of Congress, lay any Duty of Tonnage, keep Troops, or Ships of War in time of Peace, enter into any Agreement or Compact with another State, or with a foreign Power, or engage in War, unless actually invaded, or in such imminent Danger as will not admit of delay.
But TX is obviously being invaded. This is a directed action by well funded organizations.
Furthermore, the US Constitution says:
The United States shall guarantee to every state in this union a republican form of government, and shall protect each of them against invasion
The escalating tensions in Texas involving Abbotist militias and the internationally-recognized Federal Government underscore the need for an immediate foreign military intervention to reinstate law and order.
I know they are doing this for the show, but I'm not sure if they are ready for the endgame.
