For the past ten years, the U.S. military has focused on fighting wars in Iraq and Afghanistan, as well as the global struggle against al Qaeda and its affiliates. In that time, the U.S. officer corps has spent more time doing and less time thinking. As the war ends in Iraq and the one in Afghanistan winds down, the U.S. military will increasingly face the task of preparing for future wars. Indeed, a strategically and operationally proficient officer corps will be vital to our military effectiveness. However, achieving such a goal will require serious effort as well as leadership within the Department of Defense and Congress.
