Terrorism is the idea that if you scare the hell out of enough people the rest will meekly follow orders.The whole point of Iraq is to wage a perpetual war against a vague nebulous enemy entity that by definition can never be defeated. It's a glorious success.
You know how you win against an idea like that? Make every terrorist death an object lesson. As much as I hate to, the 80's movie The Untouchables had it right: "They pull a knife, you pull a gun. He sends one of yours to the hospital, you send one of his to the morgue" Hell, even the unashamedly liberal West Wing had it right, there is no value in a proportional response. The only way to drive home the point that we, yeah, we the United States will not allow terrorism or terrorist to prosper is by brutally and systematically hunting down and killing terrorists. In Tom Clancy's book Rainbow Six, there is a truly great line, during a discussion on terrorist motives, a character says, "There is only one thing we need to know about terrorists: How to kill them." Their motives and thought processes are not important, the fact that they willingly target non-combatants is enough to warrant their deaths.
Sadly, the politicians haven't shown the stomach to do what needs to be done to rid the world of terrorism.
Sometimes we have to take steps, that we would rather not in order to accomplish something worthwhile. I know, its sad and oft times ugly, but, it is reality and the sooner more people face it, the sooner we can get the job done.
Had the US not dropped the Atomic bombs on Hiroshima and Nagasaki, the Japanese troops would have fought on longer. The easiest way to stop violence is with overwhelming violence.
