Diplomacy in irregular warfare (IW) is not a supporting act; it is one of the main ways the United States competes for power and legitimacy below the threshold of conventional war. That claim matters even more now because the ongoing Russia-Ukraine war has shown that contests over legitimacy, sanctions, coalition management, information, logistics, and economic resilience are not ancillary to war; they are central to it.
