What has come to be called a “strategic pivot” marks a
significant adjustment in U.S. military and national security
strategy. When the last U.S. combat forces are withdrawn
from Afghanistan, nearly 14 years will have passed since
September 11, 2001. During this time, the weight of U.S.
national security efforts has been focused on combat operations
in Iraq and Afghanistan, counterinsurgency operations in
those and other theaters, and a worldwide campaign against
terrorists who threaten the United States. These efforts not
only draw very heavily on the nation’s military forces, but on
its diplomatic and intelligence resources as well.
