Oslo, Dec 10: US president who arrived in Norway to receive his Nobel Prize for Peace defended his decision to send more troops to Afghanistan claiming that it was a step to bring peace to the country plagued by war and violence.
Coming down heavily upon skeptics who questioned his decision to move 30,000 military personnel into Afghanistan along with the plan to initiate withdrawal of troops in 2011, Obama said that he was 'unambiguous' about the date clarifying that there would be no more debate over it.
Accompanied by his wife Michelle Obama, the president first went to the Norwegian Nobel Institute to sign the guest book.
Saying that he was honoured to receive the peace prize, the president paid tribute to the work of the Nobel committee in the guest book.
On a more modest note, Obama said that there were others who were probably 'more deserving' of the 2009 Nobel Prize for Peace.
