I was fairly non-interventionist before 9/11, and still have some qualms, but I also think that the United States has to defend itself.
Absolutely!! And self-defense starts overseas. I would never advocate intervention just for the sake of it. I truly believe that our assault on Al-Qaida and the Taliban has saved American lives. We will never know who and how many, but I believe that there are people in America who will now live a full life because of the damage we inflicted on that organization.
