The rules-based international order that has furthered global prosperity and security is not self-sustaining. As challenges to that order multiply around the world, there is no substitute for robust American engagement to ensure its preservation. Though America has many effective tools of global influence, including diplomacy and economic engagement, all of these are critically intertwined with and dependent upon the perceived strength, presence, and commitment of U.S. Armed Forces. $487 billion in cuts to national defense under the Budget Control Act (BCA) of 2011 and billions more under sequestration constitute a serious strategic misstep. These steep cuts have sharply reduced military readiness, led to dangerous investment shortfalls in present and future capabilities, and prompted our allies and adversaries alike to question our commitment and resolve. China's rapid military modernization is tilting the balance of power in the Asia-Pacific. Russia's aggression threatens Europe's regional security. Iran and North Korea continue the pursuit and development of tactical weapons, and violent Islamist extremists are destabilizing large swaths of the Middle East and North Africa while plotting attacks against the United States and our allies.
