America's top military officer has said speculation over the US withdrawal from Afghanistan could 'encourage the enemy'.
General Martin Dempsey said talk of a full withdrawal could lead Afghan forces to make 'accommodations' with the Taliban, the BBC reports.
According to the report, President Barack Obama warned that the United States might pull all troops out of Afghanistan in 2014 if a bilateral security agreement (BSA) was not signed.
But Afghan President Hamid Karzai has so far refused to sign the agreement.
Gen Dempsey said that he expected the Taliban to become more aggressive during the summer fighting season, the report added.
