Sharing is not always good

It depends on whose doing the sharing.  For example, many terrorist groups have adopted the al Qaida label and are working together: cooperating with each other, sharing money and guns, training together, advising each other and, most critically, sharing a deep-seated hatred of the West. These groups are operating in Yemen, Algeria, Mali, Pakistan, Somalia and Nigeria.

While they have adopted the al Qaida label, these groups are self-motivated; they do not need orders from al Qaida itself. Most of their strikes have been local.  However, can the day when they go beyond their frontiers be far away?
