These groups also have no real plans for the multiple political and economic problems that beset much of the Islamic world. And they won't engage in normal politics such as elections believing them to be "un-Islamic."
This is invariably a recipe for irrelevance or defeat. In not one nation in the Muslim world since 9/11 has a jihadist militant group seized control of a country. And al Qaeda and its allies' record of effective attacks in the West has been non-existent since 2005.
With threats like these we can all sleep soundly at night.
