President Barack Obama looked forward to the end of America's longest war, that in Afghanistan, as he marked the sacrifice of fallen US warriors on Veterans Day.
Speaking at Arlington National Cemetery, Obama said US troops would continue to return over the coming months, before the withdrawal of most NATO combat troops by the end of 2014.
"This winter our troop levels in Afghanistan will be down to 34,000," he said.
"And by this time next year, the transition to Afghan-led security will be nearly complete. The longest war in American history will end."
Washington is negotiating with the Afghan government to secure an agreement on leaving a residual force behind to train the country's fledgling armed forces and for possible anti-terror missions.

Obama paid special attention to the recent sacrifices of the "September 11" generation of American troops, who enlisted after the attacks by al-Qaeda on New York and the Pentagon in 2001.
"Today we can say that because of their heroic service, the core of al-Qaeda is on the path to defeat, our nation is more secure, and our homeland is safer."
Obama's changing rhetoric on al-Qaeda has encapsulated the evolving threat from the organisation and its affiliates.
Before his re-election race last year, Obama often said the extremist group was "on the run", had seen its leadership "decimated" or was "on the path to defeat" due to his anti-terror policies.
But these days his terminology is more circumspect following a string of attacks by al-Qaeda inspired or affiliated groups in Africa, Syria and elsewhere, despite the US success in largely dismantling the senior leadership that plotted the September 11 attacks.
At Monday's ceremony, Obama also highlighted the remarkable life of 107-year-old World War II soldier Richard Overton, believed to be the oldest remaining American veteran of the conflict.
"He was there at Pearl Harbor when the battleships were still smoldering," Obama said, of Overton, an African American.
"He was there at Okinawa. He was there at Iwo Jima."
"When the war ended, Richard headed home to Texas, to a nation bitterly divided by race, and his service on the battlefield was not always matched by the respect that he deserved at home.
"But this veteran held his head high. He carried on and lived his life with honour and dignity," Obama said.
"This is the life of one American veteran living proud and strong in the land he helped keep free."
