I've never liked "terrorism" as the term for our enemy. That's a tactic, not a movement. I've been using "Islamofascism" to get the key connotation that these are people who want to set up a theocratic dictatorship. Reason magazine has an interesting piece arguing that "Jihadism" should be the proper label. I've got qualms about that. Jihad is such a central tenent of Islam that war against "Jihadism" could be seen as declaring war on Islam itself. Which it may come to, but I'm hoping to avoid that.
