Here’s what seems to be a reassuring reality: The U.S., notes In Homeland Security, is separated from Europe and its “porous” borders by an ocean, making America relatively safer from the kind of marauding terrorist violence that hit Paris. Moreover, the FBI has been keeping track of Americans (about 250) “who have traveled to Iraq and Syria – or at least attempted to –” and FBI officials “have privately expressed confidence that they have those U.S. individuals contained and that the remaining Americans in Syria won’t be returning to this country unless they’re in handcuffs.”
Fair enough. Yet we’re not invulnerable. Preparedness and vigilance remain the order of our threatened times.
