NYT's Thomas L. Friedman speaks with President Obama about how the United States can be a benevolent force in the world. Obama also said, "Something I said earlier serves as a warning to us. And that is, societies don't work if political factions take maximalist positions. And I have to say here that I've been speaking in generalities and trying not to be too political, but that ideological extremism and maximalist position is much more prominent right now in the Republican party."
