Finally, the end of the war in Iraq and the transition from combat operations in Afghanistan to a military advisory role mark a shift in approach to securing U.S. interests in both countries. In Iraq the United States will not leave behind a sizable residual force to train and equip Iraqi security forces. Instead, the United States is forging a new, more normal relationship with Iraq. Its security assistance will be under State Department control, including the 250-400 military personnel in the Office of Security Cooperation-Iraq. In Afghanistan the U.S. military commander is preparing a plan to transition NATO forces out of a combat role and into an advisory role as they decline in number.
Taken together, these key events illustrate a substantial shift in the way our nation is employing its power. Out are invasions and occupations by large U.S. ground forces. In are supporting partners and using unique, over-the-horizon capabilities such as airpower, drones, and special operations forces to achieve U.S. objectives. This shift in approach should prove more sustainable in terms of domestic support and spending than the multiyear, trillion-dollar counterinsurgency campaigns pursued throughout the past decade.
The implications of this approach should be felt primarily in the defense and intelligence budgets as they face tight fiscal times. Investments should flow toward capabilities such as airpower, ships, cruise missiles, drones, and special operations forces that allow the United States to conduct over-the-horizon strikes and support missions rather than large ground forces suited to fighting lengthy irregular wars. Robust ground forces will of course still be necessary to deter countries with dangerous ground forces close to key allies such as those arrayed by North Korea along the DMZ on the Korean peninsula and to advise partner militaries, but resources should be more dedicated to those areas that better facilitate the new approach.
In 2011 President Obama crafted a new doctrine for the United States' use of force, but this doctrine is more apparent in his administration's actions than in his speeches. The new doctrine effectively removes counterinsurgency and nation-building as the main approaches to advancing American national interests and replaces them with partnering with allies and leveraging America's unique, over-the-horizon military capabilities. This new approach reduces the burdens on the United States in terms of high military casualties and out-of-control military spending while playing to its diplomatic and military strengths.
Regardless of the more controversial aspects of this approach such as drone strikes, President Obama has crafted a more sustainable way for the United States to use its hard power to advance its interests in the world.
