Through an analysis of transnational criminal networks originating in South America, this report presents operational characteristics of these networks, strategic alliances they have established, and the multiple threats that they pose to U.S. interests and to the stability of the countries where they operate. It also identifies U.S. government policies and programs to counter these networks and examines the military’s role in that context.

In this report, RAND researchers analyze Russian core interests and views of the international order. The authors find that Russia sees the current international order as dominated by the United States and as a threat to some of Russia’s interests. For several areas, U.S. and Russian interests overlap and cooperation is feasible. In other areas, U.S. and Russian interests conflict, and this report offers options for U.S. policy going forward.

A review of the scientific evidence on suicide postvention (organizational responses to prevent additional suicides and help loss survivors cope), guidance for other types of organizations, and the perspectives of the family and friends of service members who have died by suicide provide insights that may help the U.S. Department of Defense formulate its own policies and programs in a practical and efficient way.

To support U.S. Department of Defense (DoD) efforts to create a unified, comprehensive strategic plan for suicide prevention research, a RAND study cataloged studies funded by DoD and other entities, examined whether current research maps to DoD’s strategic research needs, and provided recommendations to encourage better alignment and narrow the research-practice gap when it comes to disseminating findings to programs serving military personnel.

Little has been reported about “military caregivers”—the population of those who care for wounded, ill, and injured military personnel and veterans. This report summarizes the results of a study designed to describe the magnitude of military caregiving in the United States today, as well as to identify gaps in the array of programs, policies, and initiatives designed to support military caregivers.

This report synthesizes the available scientific evidence on the effects of various firearm policies on firearm deaths, violent crime, the gun industry, participation in hunting and sport shooting, and other outcomes. Based on this synthesis, the authors highlight policies whose effects are better supported by evidence and areas where more and better information could contribute to establishing fair and effective gun policies.

Russia’s manipulation of Ukraine, which culminated in the 2022 invasion, demonstrated that Russia was willing to resort to all means necessary to secure a regional sphere of influence that included Ukraine. But events could have taken a different direction. Using the concept of national identity as a starting point, RAND researchers developed a framework to illuminate the underlying causes of the Russia-Ukraine war.

Why do some individuals engage in political violence in Yemen, while others do not? We examine the role that social, political, and economic factors play on individual behavior toward violence in the midst of Yemen’s bloody and multiyear civil war. We use a unique national survey conducted in Yemen in 2016 to better understand why Yemenis may reject political violence despite persistent conflict and civil unrest across the country.
