Petraeus Explains US Withdrawal Plan for Afghanistan VOA News 16 June 2010 US Central Commander Gen. David Petraeus testifies on Capitol Hill before the Senate Armed Services Committee, 16 Jun 2010 Photo: AP US Central Commander Gen. David Petraeus testifies on Capitol Hill before the Senate Armed Services Committee, 16 Jun 2010 The head of U.S. Central Command says President Barack Obama's withdrawal date for U.S. troops from Afghanistan will be the beginning of a process and not a rush to exit. General David Petraeus told the Senate Armed Services Committee Wednesday that the July 2011 withdrawal date signals the beginning of an orderly, responsible U.S. drawdown and transition to Afghan forces. He said the rate of withdrawal would be determined by the conditions on the ground. Arizona Republican Senator John McCain questioned General Petraeus about the date and said the U.S. was "sounding an uncertain trumpet to our friends and enemies." Petraeus briefly collapsed while testifying before the panel Tuesday. He quickly recovered but the hearing was put off until Wednesday. In his testimony Wednesday, Petraeus compared fighting the insurgency in Afghanistan to riding a roller coaster, with lots of ups and downs. He said that in Afghanistan there is no hill where you will plant the flag and go home to a victory parade. He said, rather, success in the conflict is marked by the absence of violence, such as fewer car bombings. The hearing was called to assess the situation in Afghanistan as thousands of U.S. troops continue to arrive in the country. An updated assessment of the war, now in its 9th year, is due in December.  Some information for this report was provided by AP .
