In middle school I had a social studies teacher claim that the US constitution gives individual states the power to declare war if they’re attacked by a foreign power. He said that this was because in the 1700s communication could take weeks and the Founding Fathers wanted states to be able to defend themselves without waiting to hear back from the federal government. Is that actually true?
Article I, Section 10 of the Constitution does indeed say that “No state shall, without the consent of Congress… engage in war, unless actually invaded, or in such imminent danger as will not admit of delay.”
The Constitution says nothing of states “declaring” war, that is a power specifically reserved to Congress in Section 8.
If a stete is ettecked, it doesn’t declere “was”; it decleres “were”!
