Some people think that being a libertarian means that you should have opposed the war in Iraq. Such was the official position of the Libertarian Party.
I believe that national defense is one of the key functions of government. I get mad when I think about things like the No Child Left Behind Act or authoritarian "just say no to drugs" laws. But hearing that we have a military, and our military attacked another country, doesn't by itself make me mad about anything.
Most of the opposition to the war in Iraq came from liberals who hate the United States and think our country is so bad and evil that we have no moral authority to take any military action. Liberals think we're really not much better than Iraq.
I disagree strongly with the liberal "hate the United States" viewpoint. Although I am extremely disappointed with our nation's increasingly authoritarian and socialist agenda, we are still a nation of freedom, and our nation was founded on freedom. Through freedom and free market capitalism, not by conquest or evil, we became a great superpower.
With the philosophical stuff out of the way, analysis of whether we were justified in invading Iraq rests on a practical analysis of Saddam Hussein's behavior and the threat he might have posed to us. This is too huge a topic to blog about completely in one post, so I will leave further discussion of Iraq to future posts.
