Obama: "[In my Nobel Peace Prize speech] I wanted to make an argument that didn't allow either side to feel too comfortable."

Joe Biden: "[Obama] is an intellectual. ... He's not a moralizer."

Ahmadinejad: "[I like] talking and listening with a calm manner and a logical reasoning."
Ahmadinejad: "I am worried at the thought that [progress] would be sacrificed for the stagnant mentality, action-dodging and conservatism of some people."
