Why can't we kill our way out of this?
Iraq and Afghanistan worked out well.
We're fighting an ideology. We need to put a boot on their necks but we're kidding ourselves if we think that's the only solution.
Climate and economics may contribute to the conditions that lead to terrorism, but the one most obvious contributor is Islamic terrorism is the one no one wants to talk about: the cultural influences that drive people to those groups and to commit those acts, namely, the religion of Islam.
Which is what I'm saying. The "soft" issues are contributing to the rise of Islamic terrorism. They aren't the sole cause and I'm not so blind as to think that. Social or physical issues are making the Islamic world more open, for lack of a better word, to terrorism.
Adverse conditions will see humanity reduced to basic levels and they will choose good vs. evil. The Siege of Leningrad is a great example. People stuck together or they resorted to cannibalism, there was little middle ground. History is littered with people who reached the end of their ropes and decided to get the kill on. To kill our way out of the Middle East would involve killing damn near every Muslim in the ME and that is impractical. We need to drop bodies but a long term solution will require more. We simply can't (we need to be realistic here. All of the talk of nuking this or that is just stupid) kill enough to bring about peace.
