It's really not too complicated. A militia is a citizen military force (the Lexington Minuteman) in contrast to a standing professional army (King George's lobster-backs). Well regulated means it is not to be an aimless mob much like the soon to happen French Revolution. The only way this can be guaranteed is by having the power distributed among the people with state of the art assault rifles. Imagine the American militia fighting the British professionals with greatly inferior arms. There would be no America. This means no infringement.
You really can't trust anybody else. You can't trust Bush's New World Order anymore than you can the Kennedy's Camelot.
I happen to think Bush’s NWO is pretty damn good. Kill islamo scum in their own countries, change the official federal gov’t position on 2A to proclaiming it an individual right, and scuttling the UN Small arms treaty. that’s the kind of NWO I like.
