There is a tendency, among subgroups in an open source insurgency, to increase local cohesion at the expense of whole. Usually this is done by disrupting social networks to create antagonism between member groups. The order is:
...don't fork the insurgency...
Social network disruption is nearly as easy as disrupting physical networks, but it can be very dangerous. Social network disruption should only be used if it cleaves the nation-state into non-cooperative centers of gravity without sacrificing open source cohesiveness. In contrast, social network amplification is almost always good.
NOTE: This is grand strategic mistake of al Qaeda in Iraq (unlikely to be repeated). As I mentioned in my 2005 NYTimes OP-ED entitled The Open-Source War: "there are few visible fault lines in the insurgency that can be exploited." That was true until attacks on Shiite civilians and ultimately the Golden Mosque attack forked the insurgency.
