Hahaha, I agree... as long as the proposed invaders come in a-horse-back, sporting muskets
... just imagine trying to defend yourself in the backwoods from what our country is using against the Afghanis right now...
Satellite surveilance, drones, FLIR, anti-personell armaments capable of pinpoint accuracy at night from MILES away...
How are you gonna fight that other that go to the source and do what you can.
