Occasionally, you read something that lets you better understand somebody else's thinking.

Obama, as quoted at Gateway Pundit:

--I think you are privatizing something that is what essentially sets a nation-state apart, which is a monopoly on violence

Of course, the U.S. Constitution's Second Amendment is all about ensuring that the state in fact does not have a monopoly on violence.  Should the state become sufficiently tyrannical, it is the right (and, perhaps, the duty) of the people to dissolve it--that comes from the Declaration of Independence.

States very seldom dissolve peacefully.  Just ask the Iraqis about that.
