 Now, for the U.S.-Russia relationship, which I'll talk about mostly in my few minutes, for the reset, there have been three key issues on security relations that have been driving the Obama administration's desire to improve relations with Moscow. The first and most important has been Iran and the urgency of their nuclear weapons program. The second has been Afghanistan, and the much larger bet that the Obama administration has placed, or higher priority, the Obama administration has placed on winning the war in Afghanistan, and therefore the role the Russians play in providing supply and transit of materials, both lethal and non-lethal, to our troops in theater. And the third is, of course, the nuclear security agenda, which, without making progress with Russia, is impossible to move forward on. I think there's no question, as we look at, you know, the 15 months or 14 months since the Obama administration has taken power, that the U.S.-Russian relationship has improved considerably. Now, it's improved from a very low point. It's a very low bar. In fact, if the relationship had not improved, which it was basically frozen at the end of the Bush administration after the war in Georgia, there was the danger, literally, of a new cold war. This security summit next week will focus on the weapons-usable material. There is enough material, depending on who you talk to, for between 120,000 weapons, or 300,000 weapons. That range demonstrates right there that we need to do more. We need to exchange more information. There needs to be a lot more transparency. And this is a job that is for all countries, not just nuclear weapon states, not just nuclear weapon holders like India, Pakistan, and Israel, but for all states. And so, going back to the agreement on what the threat is, one of the functions of this summit will be to get greater agreement on the fact that there is a threat, to get all countries to say, yes, we agree, this is a problem. So the White House hopes for four things, that countries will be engaged. They will be more aware. They will pledge to do something about this. They will adopt best practices. And they will provide assistance to other countries.
