This paper establishes that the national security environment requires that we operate together. The imperative to unified action applies across the whole United States national security enterprise, and extends to international and multilateral fora. Leaders can apply insights drawn from theories of social network analysis, organizational culture, and organizational traps to better understand common organizational dynamics which affect cooperation between organizations. Taken together, these tools arm senior leaders with a way to achieve greater impact and effectiveness when they work in the interorganizational space. This will lead, in turn, to outcomes which advance the nation’s interests and security.
