I've frequently pointed out that all government and law is, at bottom, a prediction or warning of the application of force, or the actual application of force. The only difference between force applied by the government and the thug who threatens your life if don't hand over your cash or belongings, is that government claims a moral right, and the governed generally concede that the government's application of force is moral. Otherwise, force is force, and it doesn't feel good if you are on the wrong end of it.

If the source of immoral force is your enemy, then -- our government is our enemy. The only distinguishing factor is whether or not you, in particular, have been singled out for government action.
