The Art of Irregular Warfare Campaigning: A Job for Which Headquarters or Agency?

Irregular Warfare (IW) Campaigning is the art of using available resources by the Department of Defense and other Agencies in a series of linked actions, over an extended period, to eventually gain a marked advantage over your adversary, who will also be referred to as peer competitors. This long-term strategy requires continuity of desired end states through both political administrations and military command rotations. This was done by and large during the Cold War, albeit with course adjustments; the key was that the majority of America never questioned that the Soviet Union was our number one enemy. This basic common focus during the Cold War helped facilitate a unity of purpose and effort from different organizations, if not a unity of command and priority of tasks. So, the question is what agency or headquarters should take the lead in IW campaigning in the present multi-polar complex world?
