So the only way we are looking at an outside attack if if it is coordinated by our own government.

Is that possible? I don't think so because there are still 400 million or so firearms in this Country. Does anyone really believe that the 1-2 million vets would just sit there and let an invasion happen without fighting back in some way?

Stop an think people. Logistically America would be a nightmare to attack. Armies MUST have supplies to operate. LOTS of supplies.
