The War in Afghanistan continued. In September 2008, President Bush announced he would shift 4,500 U.S. troops from Iraq to the conflict in Afghanistan. This was followed with recently elected President Barack Obama announcing in February 2009 that the United States would deploy an additional 17,000 troops to Afghanistan. The Obama administration also later announced a "troop surge" of an additional 30,000 U.S. military forces to be deployed in the summer of 2010, and to begin withdrawals of the 100,000 total U.S. troops in July 2011. With the surge in effect, the NATO-led International Security Assistance Force (ISAF) launched Operation Moshtarak, an offensive determined to eliminate Taliban insurgents from Helmand Province. At 15,000 troops, it was the largest joint operation of the war.
