One of the things you learn as president is, as powerful as this office is, you have limited bandwidth. And the time goes by really quickly and you're constantly making choices, and there are pressures on you from all different directions - pressures on your attention, not just pressures from different constituencies. And so you have to be pretty focused about where can you have the biggest, quickest impact.

With respect to Russia, my principal approach to Russia has been constant since I first came into office. Russia is an important country. It is a military superpower. It has influence in the region and it has influence around the world.
