What was the most interesting thing to happen at the G20?

Has to be Ivanka and her breakthrough global climate deal, which of course didn't happen. No she didn't do anything while she was there, but I mean she annoyed Christine Lagarde, a little bit different story. The big deal was of course the world's two largest economies: U.S. and China. We have a cease-fire on further trade escalation, though absolutely no agreement on technology. I don't think there's going to be one there and when the relation is going to be very tense going forward, but it's important that take a step back from what had been escalation.

Will the US settle for a nuclear freeze by North Korea?

I don't know if they'll settle for a nuclear freeze but we now do have a willingness on the part of the American president to engage in incremental discussions in other words maybe the North Koreans do a formal freeze of ICBM and nuclear testing maybe they allow some inspectors in, they closed some plants, and the U.S. pulls some sanctions off. That was a non-starter in the first two summits. It's now becoming a possibility. It's the only way you get a deal with the North Koreans, moving in that direction.

Can Iran convince Europe to provide sanctions relief?

No. The Europeans would like to do that. The Americans have all the cards. That's why the Iranians, a year after the Americans pull out, have finally decided to start breaking their own nuclear agreement. The Americans, of course, broke it first.
