With the implication being that they can declare war if somebody invades them. Somebody like, oh I don't know... Mexico? As in if the state government decided that the ridiculous levels of illegal immigration constitutes an invasion, would they not have the power to declare war on Mexico?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.
-Article I Section X of the U.S. Constitution
All the evidence is there. Mexican nationals are illegally crossing the border in massive numbers and occupying American territory, and the Mexican government is actively aiding and abetting these trespassers. This means the Mexican government is more or less responsible for an invasion of the U.S. As far as I can tell, then, any state would be perfectly within its rights to call out Mexico.
I know it won't happen and I certainly don't wish for it to happen, but the Constitution is pretty clear. If in the unlikely event **** hits the fan and something like this happens, do you think a state could get away with this legally? What would the federal government's reaction be? Would you support such action or would you think the state in question has lost its marbles? How would Mexico react?
