The United States of Islam is not in the USA (or at least not YET).
So where will it be? Obviously the MB is a front for one or more arab states, who are destabilizing neighboring countries with the intent of taking them over (think Warsaw Pact).
Who's behind it? My first guess would be Iran. And who are the current targets? Look for internal revolts, like Yemen, Libya, Egypt, Qatar...
