The current international security environment is characterized by unprecedented uncertainty. In the Asia-Pacific, our allies adjust to China's rise and hedge against instability coming from North Korea. In the greater Middle East, the Syrian civil war draws in powerful state and nonstate actors, Iran's weapons program worries its neighbors, the Arab Spring continues its uncertain course, and we see a growing Sunni-Shia split throughout the region. In Europe, the need for a strong North Atlantic Treaty Organization alliance has become clear as nations along Russia's periphery reevaluate their strategic alignments in the wake of the situation in Crimea. In Africa, weak states with ethnic and religious tensions set conditions for terrorist groups to operate with near impunity. It is in this uncertain and unstable world that U.S. military forces will operate for the foreseeable future.These security challenges require us to remain the most highly-trained and professional All-Volunteer land force in the world, uniquely organized with the capability and capacity to provide expeditionary, decisive Landpower to the Joint Force, and ready to perform the range of military operations in support of combatant commanders to defend the Nation and its interests at home and abroad, both today and against emerging threats.
