We dominate a vacuum of power. The Air Force's only rival in the air is the U.S. Navy, owner of the world's second-largest air force. On the seas, the Navy is unrivaled but continues to add ships to the fleet. In this vacuum, members of Congress challenge each service to outspend each other, far beyond what is feasible for true national security. Secretary of Defense Leon Panetta noted, "you've also got to take into consideration the national security threat that comes from the huge deficits and the huge debt that we're running." We cannot afford to avoid tough decisions when it comes to our budget. We certainly can't afford to give each branch of the military a blank check for weapons systems we don't need.
