I keep hearing about how "freedom isn't free." I agree, but the real war is not in Iraq. The real war is here at home. "Our way of life is threatened." Our way of life - the concept of personal liberty - has been under assault for over a hundred years!
The enemy isn't an Iraqi, and the enemy cannot be defeated with violence.
The enemy is your neighbor or family member who thinks their concept of morality should be imposed upon you under color of law, even when your actions cause no harm to others. Sure, it's okay to drink yourself blind, but don't you dare shoot some cocaine in your arm!
The enemy is your coworker who thinks it's fine that the federal government takes a chunk of your paycheck every week, and a larger chunk at the end of the year.
The enemy is your girlfriend who doesn't understand how the popular election of U.S. Senators has unbalanced our Congress and accelerated our fall towards bread and circuses.
The enemy is your brother, who doesn't think you should have a machinegun because you "might" hurt someone. He would, after all, and he projects his lack of self-control on the world.
We need out of Iraq. We need out of the world in general. Avoiding foreign entanglements, except in the times of most dire necessity, is the only way to protect our freedoms long-term.
As RotM says, know your enemy. Know that education is the only way to fight them.
