In the United States we have the much-maligned color-coded National Threat Advisory level, which has basically moved back and forth between ‘Elevated’ (yellow) and ‘High’ (orange) since it was established. Other countries have similar systems with various nuances, but they’re all apparently designed to give you a general idea of how likely you are to be blown up by a terrorist on a given day.
I can’t figure out what purpose they’re supposed to serve. As best as I can tell, they’re just a kind of ‘general information’ deal to let us know when there’s an increased risk of terror attacks, but I’m not sure what we’re expected to do about that. Invariably, we are told when the threat goes up that we should just go about our business like normal. Right now, threat levels in Europe are up and the U.S. State Department is warning U.S. citizens that al-Qaeda is planning attacks in Europe . . . yet, at the same time, State Dept. officials are saying, “We are not, repeat not, advising Americans not to go to Europe. We’re not saying don’t visit major tourist attractions or historic sites or monuments.”
So Europe is dangerous and at immediate risk of terror attacks, but we should go there anyway and not change any plans. Clear as mud.
