Believe it or not, the fate of the free world hangs in the balance as we speak. Terrorism has touched our lives in ways we could never have imagined September 10th 2001. Terrorists have shown us that nothing is sacred and nothing is safe. Many have characterized the current situation as being "at war". Our enemy is amorphous and scattered. They have no formal chain of command - no head to cut off. The only intelligible communication they attempt to make is the language of violence - They open their mouths and mayhem pours out.
Given the situation, I amazed that their are people so foolish as to suggest we should capitulate to their demands. People who want to bring our troops back from Iraq, who want to blame the policies of the United States for inciting men to terrorism, who believe that there was no justification for military forces to attack Iraq, and who believe there is no reason for them to be there now. I'd like to ask: "What the f**k are you thinking?"
Whether are not Saddam Hussein had any connection with terrorists before his regime was toppled like so many stacks of so many cards, there are terrorists in Iraq now and they want us gone. What we are doing to them is effective. The US Army is hitting them where it hurts. Really. Leaving would allow them to declare victory just like they did in Mogadishu, Somalia. Leaving now would cost innocent lives (their is no more cliche phrase than the phrase "innocent lives" but well for lack of a better one) in the future. The election of a government in Spain that does not support the war in Iraq is dangerous. It's capitulation. People will die.
