Obama's swan song at the United Nations

At the General Assembly today, Barack Obama delivered his final address as President of the United States. He said, "The existing path to global integration requires a course correction… But I believe America has been a rare superpower in human history insofar as it has been willing to think beyond narrow self-interest. That while we've made our share of mistakes over these last 25 years -- and I've acknowledged some – we have strived, sometimes at great sacrifice, to align better our actions with our ideals. And as a consequence, I believe we have been a force for good."
