1. Because obviously whatever is being done isn't working. Remember, the threat is worse, not better. We're not even distinguishing good from bad terrorism. We lump it all into the same category and assume it's negative. That's why the IRA decided to be political and not militant and why everyone is so worked up about Greece's revolutionary groups.

2. That's an entirely different argument, but I'll address that with #3

3. You mentioned that Islam is naturally violent, yet now you say the cause is an area where buying an AK-47 is as normal as buying a new car (except less expensive). I agree. It's not necessarily politically incorrect to say the Middle East has always been a place of turmoil, but religion isn't the key reason. Momentum is. Get a ball rolling, it won't stop. Likewise, start a war, it poisons relations and minds of everyone for generations to come.

4. War isn't run by opinion polls. War is run by generals and politicians, and because most military commanders know what works and don't have as many ulterior motives, I trust them over politicians.
