We support Israel, and they hate Israel. Ergo, they hate us. Its basically that simple.

RP talks about how our interventionist foreign policy is what is causing terrorists, etc. to hate us. AND if we were to simply stay in our own country they wouldn't have animosity towards us.
This is true. Its also incredibly narrow sighted. We support Israel. They hate Israel. Ergo, they hate us. We support Israel for a variety of reasons, but namely because 6 million of their people were recently exterminated and we have a large jewish and Israeli population in America which pressures political officials to support Israel and ensure it doesn't happen again. Bin Laden and the like of course would LOVE for it to happen again.

Fundamentally, it's that simple.

We have certainly compounded the issue with Iraq, and yup in hindsight it was a fucking terrible decision, but simply up and leaving Iraq will not make terrorism stop, in fact it would probably drastically increase as terrorists will believe they beat America in Iraq and they can beat America somewhere else. Their recruiting message will become stronger.

Right now terrorists are dying in Iraq. Whether theyre dying faster than theyre being recruited is up for debate, but no one can deny they are dying. And fundamentally, its hard to recruit people when there is a significant chance they could die (Right US armed forces?). Right now terrorist recruiters have to convince young impressionable men that the risk of death is worth the reward (killing americans, 72 virgins, yadda yadda). I think its plain to see that if we remove the significant risk of death, it becomes an easier risk v reward calculation.

There is no simple answer. Right now, there is no real good answer at all.
