A state’s right to defend itself
According to Article I section 10 paragraph 3 of the US Constitution:
“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.”
The state of Arizona can deploy the National Guard to it’s border to reclaim the areas ceded by Obama and Janet Napolitano to Mexico.
Any comments?
