"What we're fighting against is these long-term trends in which being selfish, being tribal, being divided, and seeing others as an enemy - that has become a stronger impulse in American life," Obama said.
"It's part of the reason why the response to this global crisis has been so anaemic and spotty. It would have been bad even with the best of governments.
