Let me explain my optimism regarding an operation of this nature. First off it would happen during peacetime meaning that any bloodshed instituted by the aggressor spells murder. Blood that’s shed by the aggressor spells self defense. How many people are ready to murder? Especially a fellow American.
Not saying you are wrong, but go look how things are phrased in the past.
If say, the troops were told there was an emergency and they HAD to disarm the area, they will probably do it with little question.
It is a long used tactic.
