That side? Liberalism considered talk to be the same as action.
President Obama has just been given the Nobel Peace Prize. It was given to him for giving "hope for a better future", including reducing nuclear arms and talking with Iran about peace.
But Obama has only TALKED about reducing nuclear arms (which will not actually improve peace, since the radical nations will not give up theirs, but that's another matter), and he has TALKED about meeting with Iran. He has not actually done EITHER. Other Presidents have DONE both; Obama has TALKED about doing both.
