I don't think you should get downvoted for sharing your opinion, but who do you really think would benefit from regulating firearms? There is a very good reason the constitution provisioned firearms and I think people are starting to forget.

All citizens that wouldn't be killed: * by mistake because it found one in a cupboard? * by someone who gets to discharge his feelings?

if you think people with automatic rifles are going to be anything other than a minor annoyance to an organized army you're in for a shock. On this very site there's been articles about the gorgon stare. Rifles don't compete against that technology.

All true if you think terms of taking and holding territory, not true at all if you step away from the geographic paradigm. The US military is very powerful against other states but ultimately it's a force that clings to Clausewitzian doctrine in a Boydian world.
