JONATHAN KARL, ABC NEWS: Mr. President, thank you. In China, in Syria, in Egypt, and now in Russia we've seen you make strong statements, issue warnings that have been ignored. Are you concerned that America's influence in the world -- that your influence in the world -- is on the decline? And in light of recent developments, do you think Mitt Romney had a point when he said that Russia is America's greatest geopolitical foe, if not Russia, who? And Mr. Prime Minister, do you think these sanctions will change Vladimir Putin's calculation? Or cause him to back down. Where do you see a Russian red line where if they go any further, into Eastern Ukraine, into Moldova, when would options beyond sanctions have to be considered?
BARACK OBAMA: I think if the premise of the question is that whenever the United States objects to an action and other countries don't immediately do what we want, that that's been the norm, that would pretty much erase most of twentieth century history.
