Do you really believe that they can defeat us?
Oh ye of little faith.
The Japanese didn't invade us because they knew that they American public would be as formidable a foe as the American military. We are an armed populace. Do you think that we'd just sit by and let them -- or any invader -- just roll over us?
Do you realize that the only proven (publically known) attack against us that was thwarted was thwarted by civilians? I know that there there are reports of 'this plan' or 'that plan' was disrupted and they might even have existed. It's to the enemy's advantage to cause fear. It's to our protective force's advantage to claim that those threats are real.
Cynical? You bet I am. Do you remember the ATF's need to be relevent about ten years ago? Do you remember Waco and Ruby Ridge? Yes. I am cynical. I do not trust my government as you do. They will protect themselves at any and all cost -- to the taxpayer.
The government will protect it's own should push come to shove. I have faith in the 2nd amendment to protect me and mine.
