You're there because your president is leading a global war against terrorism. It's all connected, don't you see? Al Qaida, Hizballa, Hamas, Islamic Jihad, Tanzim, PLO, PLF, etc. They co-operate, they share knowledge, they teach each other, train eachother. You can't declare a global war on terrorism but concentrate on one organization only. That won't solve anything, because the co-operation goes on between them. What if tomorrow another plane crashes into a building in the US, and it turns out this time Hizballa carried it out? Will you then only fight those who help Hizballa? Why not fight it now, when you know there are the motivation and plans, and make sure they don't ever become capable of doing it? Iraq's connection to terror has been proven, and that makes it a good enough reason to include it in the war on terrorism.
