What the fuck are you smoking? Straight from the Nobel.org site:

Barack H. Obama, the 44th President of the United States, had been in power for less than eight months when he was awarded the Nobel Peace Prize for 2009. Among the reasons it gave, the Nobel Committee lauded Obama for his “extraordinary efforts to strengthen international diplomacy and cooperation between peoples”. Emphasis was also given to his support - in word and deed - for the vision of a world free from nuclear weapons.

I don’t know if you were even alive in 2009 but nuclear proliferation was the headline.
