US Constitution, Article 1, Section 10, clause 3
"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."
sorry, but NO!. As a former resident of Illinois myself, your viewpoint and understanding of the Illinois Constitution is either misguided or purposefully misinterpreted.
