Your hypothetical question can only lead to hypothetical conclusions. I don't remember ever saying that we don't need a military, can you quote that or do you just make shit up? ( You make shit up)
Since we are just making shit up, I propose if we have no military that the civilians just bring out their own personal thermonuclear device and space ray gun to take care of any pesky enemy past the wire events.
Making shit up isn't really that much fun, I am not sure why you indulge in it so much.
so, in conclusion: I never said we don't need a military. Got it Mr make up shit?
