Terrorist threat is so specific that US had to close 21 embassies

How specific is the terror treat? The threat is so specific that US had to close 21 embassies. Most of the region. Under normal conditions specific threat would mean that 1 or 2 embassies had to be closed. But today it is a whole region. What are the chances it's a "phony" threat to overshadow the "phony" scandals like Benghazi terror attack? Just asking.
