Obama now in Oslo to accept Nobel Peace Prize

In Norway today, President Barack Obama acknowledged criticism of his Nobel Peace Prize on Thursday but said he hoped it would subside if he succeeded in his goals, including cutting nuclear weapons and tackling climate change.

Speaking in Norway before collecting the prize, Obama also reaffirmed U.S. troops would begin transferring responsibility for Afghan security to local forces in July 2011 but said there would be no "precipitous drawdown."

Obama will accept the prize just nine days after ordering 30,000 more U.S. troops to Afghanistan to break the momentum of the Taliban.
