Terrorism(from dictionary.com, bolds added for effect): The unlawful use or threatened use of force or violence by a person or an organized group against people or property with the intention of intimidating or coercing societies or governments, often for ideological or political reasons.
You may agree or disagree with what they are doing, but it is clearly terrorism. It is also insurgency.
>The trouble in middle east would not have bothered us a bit, if (a) Israel wasnt in the midst of all of it and (b) Oil, billions and billions of gallons of it.
The real trouble is that people see oil fields and can't think beyond that point. Superpowers, especially in the last 100 years have tried to fight by proxy, rather than fighting head to head. Proxies were used by the Soviets in Vietnam, and by the U.S. in places like Afghanistan. There are many reasons for that.
Some, such as not wanting their own troops killed, are purely selfish reasons.
Another would be the desire to not escalate a conflict to the nuclear point. The Cold War is a great example. What would have happened if the U.S. had gone head to head with USSR? For the two countries, certainly massive death and destruction. For the rest of the world, at the very least economic meltdown. At the worst, nukes would start flying with casualties in the hundreds of millions.
Was Iraq itself a dire threat to the U.S. by itself? Of course not. Their one and only hope of harming us was to purchase black market nukes or a delivery system for their old WMDs. Iraq was another proxy war. Who is the real enemy? I can make a few guesses here, and you are welcome to join in the speculation. Iran is clearly sending fighters and money to Iraq. Our friends the Saudis(some anyway) financially support terrorist groups fighting in Iraq and elsewhere in the middle east. Then you have the people in Europe who were getting rich off of the Oil for Weapons, oops, I mean Oil for Food program in Europe such as France, Germany and Russia. In the end the "real" enemy is probably Mr. and Mrs. Islamofascist all over the middle east and the world, and our weapon of choice is democracy in Iraq. We spread democracy and capitalism, people can do what they want, get a job, get educated, raise a family, and be happy. Happy people don't bomb places and kill people. And worst yet(for Islamofascists) democracy spreads.
I actually do agree with part of your post regarding the Sudan. The U.N. needs to step in immediately and try to help if they can. Genocide on any people, any where in the world should not be tolerated. However your view of the Iraq War is very short sighted.
