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."
