USA Today reports that the bombings in London and Sharm el-Sheik, Egypt, raise a question with no sure answer: Why haven’t Muslim militants executed another suicide terror attack in the U.S.? If suicide bombers can strike daily in the Middle East and hit the capitals of Europe, why does 9/11 remain a spectacular exception?
Authorities say another attack is inevitable, but so far it hasn’t happened. There are theories about why the United States still hasn’t had a homegrown attack like the ones last month in London. Suicide bombing isn’t that easy. The USA isn’t that vulnerable. American Muslims aren’t that militant. Foreign terrorists aren’t focused, not yet, on a domestic strike. Luck may also play a role.
