In this report, the authors use 11 case studies to create a typology of the barriers that impede U. S. security cooperation with highly capable allies and partners; identify some of the more specific barriers in the air, space, and cyber domains; suggest mitigation strategies for each of these barriers; and propose a preliminary approach for implementing some of these mitigation strategies.

Policy and U. S. Intelligence Community (IC) professionals have suggested that the IC is held in increasingly lower regard by some decisionmakers and that predictions have had variable success in influencing decisionmakers. Researchers explored whether and to what degree trust in intelligence predictions and national estimates has degraded over time and what factors might have driven any changes in the relationship between policymakers and the IC.

Section 1652 of the fiscal year 2020 National Defense Authorization Act tasks the U. S. Department of Defense (DoD) to perform a zero-based review (ZBR)--a detailed review rather than a simple comparison with previous size or budget--of its cybersecurity and information technology workforces. The ZBR process described in this report constitutes a transparent, repeatable process with which DoD can conduct ZBRs across the DoD cyber enterprise.
