Cameron - Afghan drawdown won't ease pressure on Taliban

U.S. President Barack Obama announced Wednesday he planned to withdraw 33,000 troops from Afghanistan by the end of next summer. After the withdrawal, about 70,000 U.S. troops will remain in Afghanistan.

During a visit to fellow NATO member Czech Republic, Cameron said it was significant that only 10,000 of the troops would leave this year, with the remainder in 2012.

"What this means is there will be no let-up in the pressure on the insurgency in Afghanistan," he told a media briefing.

"I'm satisfied that the removal of the (U.S. troop) surge will still enable us to keep up the pressure on the insurgency as we transition to Afghan control between now and 2014."

Obama's plan will bring home the entire "surge" force that he sent to Afghanistan in 2010.

Although the war is deeply unpopular among American voters, military advisers have said a rapid departure from Afghanistan is not a good idea because they fear it could allow Taliban insurgents to quickly regain lost territory.

U.S. and NATO forces, with Britain and Germany supplying the next largest contingents, have been unable to deal a decisive blow to the Taliban, which was ousted from power in Afghanistan in 2001.
