The point being, vet, is that it's long been a goal to establish a "pure" Islamic caliphate from Indonesia to North Africa and beyond.
Most of the current boundaries in Islamic nations, including Iraq and Libya, were formed based on European colonialism in the 17th through early 20th centuries.
While there is some nationalism among the leadership, most of the Islamists would be much happier with dissolving the borders knowing full well ONE Islamic state is better than 57...(kinda like Obumbler and his "57 states"...)
