The US is different. The Europeans, for all their faults, do not believe that news is something that happens on TV. When their face gets rubbed in something real and horrible, that wakes them up. America, however, is deep into the delusion of longitude. 9/11 woke America up, but since no major terror strike occurred until the Boston Marathon, America went back to sleep. The Boston Marathon worked for a while, but since that did not occur again, and nut jobs going postal with guns over grammar or breaking up with their girl friends, or what not, more frequently, America went right back to sleep soon after. To Americans now, terrorism is just another nut job going postal over something or other. This is why its allies must make other arrangements.
