Afghan President Hamid Karzai's surprising allegation that the U.S. and Taliban are conspiring together to keep the war going caught some off guard. But during his eight years as president, Karzai has frequently antagonized the U.S. government by claiming the U.S. motives for being in Afghanistan were selfish. At one point he accused the U.S. of using Afghan soil for its own goals and purposes. More than 2,000 American have been killed and more than 18,000 have been wounded.
