国际英语新闻:Obama to Announce Decision on Afghanistan Troop Drawdown

President Barack Obama will announce his plan for implementing the beginning of a U.S. troop withdrawal from Afghanistan in a speech scheduled to begin at 00:00 UTC Thursday. Mr. Obama will say he is fulfilling the commitment made 18 months ago to begin drawdown, and underscore progress toward turning over security to Afghan forces.

Leading up to the president's announcement, the White House stressed again that it would not involve any re-tooling of the strategy unveiled in December 2009 in a speech Mr. Obama delivered at the U.S. military academy at West Point, New York.

In that address, Mr. Obama set out what he called a "strategy to bring this war to a successful conclusion" and announced deployment of an additional 30,000 troops aimed at turning back Taliban advances.

"As commander in chief I have determined that it is in our vital national interest to send an additional 30,000 U.S troops to Afghanistan.   After 18 months our troops will begin to come home.  These are the resources that we nee to seize the imitative while building the Afghan capacity that will allow for a responsible transition of our forces out of Afghanistan," Mr. Obama said.

At the time, Mr. Obama noted the war's "enormous costs in lives and resources" but said he was convinced that U.S. security was at stake in what he called the epicenter of violent extremism in Afghanistan and Pakistan.

The president will reaffirm his commitment from 2009 to begin withdrawing forces.   Various reports quoted administration officials as saying at least 5,000 soldiers, about one brigade, could come out in coming months, with another by the end of the year.

Cautioning against media speculation, White House Press Secretary Jay Carney said Mr. Obama has remained focused on three objectives:  disrupting, dismantling and defeating al-Qaida, reversing Taliban momentum, and preventing Afghanistan from becoming a safe haven for terrorists.

"Those objectives are being met, we have had a significant amount of success in meeting those objectives and the president has been very engaged in the process evaluating that.  We are not there yet obviously, but it is important to remember what the objective were from the beginning and what they were not and the president will make that clear again tomorrow evening," Carney said.

Mr. Obama will reiterate the U.S. and NATO commitment of completely transferring security responsibilities to Afghan government forces by 2014.   He and military commanders have stressed that the speed of withdrawals would be based on conditions on the ground.  Withdrawal of the 30,000 U.S. surge force by next year would still leave some 68,000 U.S. troops in Afghanistan.
