Although today’s civil conflicts are very different from those of previous generations, it is not a foregone conclusion that today’s Western-affiliated rebel groups will suffer defeat. While with any new conflict the task becomes more and more difficult, it is still possible to outcompete other groups in the rebel bloc, at least right now. On the other hand, it is hard to imagine a victory of a Western-oriented, startup armed group without significant outside support, because they lack experience and resources. At the same time, international actors with a different agenda also don’t want to miss a chance to use their money, experience, and knowledge to increase their sphere of influence through proxy groups in war-torn countries. That, in sum, makes this generation’s civil wars a highly competitive market for outside supporters. I this chapter the author discusses how this knowledge can be used to terminate a conflict more quickly by making foreign government intervention more effective—in particular, how a foreign actor could (1) choose a group in the rebel bloc to support; (2) persuade the group to accept support; and (3) provide the proper help at the right time in order to empower one group at the expense of others within the rebel camp.
