America, its allies and its partners face a dynamic threat environment. Nimble adversaries have seized the initiative and are shaping an order, often in concert with one another, that threatens vital U.S. interests. Russia, Iran and a global jihadist movement are among the actors that have fueled - and exploited the effects of - an assault on the international system. The U.S. must address immediate global crises but also look beyond them to develop long-term strategies that advance the nation's security, prosperity, and liberty.
