Tora Bora
In 2009, the United States Senate Committee on Foreign Relations led an investigation into the Battle of Tora Bora. They concluded that Secretary of Defense Donald Rumsfeld and General Tommy Franks had not committed enough troops during the battle to secure the area around Tora Bora. They believed that Osama bin Laden had likely been at Tora Bora and his escape prolonged the war in Afghanistan.
