President Biden has stated that we are living in a “decisive decade,” one stamped by dramatic changes in geopolitics, technology, economics, and our environment. The defense strategy that the United States pursues will set the Department’s course for decades to come. The Department of Defense owes it to our All-Volunteer Force and the American people to provide a clear picture of the challenges we expect to face in the crucial years ahead — we owe them a clear and rigorous strategy for advancing our defense and security goals.
