Awarding the Nobel peace prize to him failed to fulfill the committee's expectations, reported BBC on Thursday.
"The committee hoped the award would strengthen Mr Obama," said Geir Lundestad in an interview.
"Even many of Obama's supporters believed that the prize was a mistake," said Lundestad. Even President Obama himself had been surprised on committee's decision.
"No Nobel Peace Prize ever elicited more attention than the 2009 prize to Barack Obama," Lundestad writes.
US President Barack Obama was given Nobel peace prize in 2009.
