In an interview published by Newsweek on Sunday, Obama said he dose not has such a plan for now, though it is still possible to add more troops in the future, he said
Obama noted that adding troops alone can't solve the problem.
"My strong view is that we are not going to succeed simply by piling on more and more troops. The military component is critical to accomplishing that goal, but it is not a sufficient element by itself," said the president.
He said future decisions on sending more troops depend on the development of Afghanistan's security and politics.
Obama said his announcement to send 17,000 troops to Afghanistan in February is the hardest decision he made since taking office in January.
Since his swearing-in, the president has ordered sending 21,000more troops to Afghanistan, and that will bring U.S. troop levels there to 68,000 later this year.
The interview was conducted on Air Force One last Wednesday, and it covers a wide range of topics, including life in the White House, Afghanistan, Pakistan, the Republican Party, former Vice President Dick Cheney, Israeli Prime Minister Netanyahu's forthcoming visit to Washington, among others.
