Let me just give you a clear example of that. Lavrov and Kerry are still talking daily when it comes to negotiations on Iran because there is no choice but to have it. In fact it's absolutely essential because what has happened, sadly, in Crimea and in Ukraine generally, could have thwarted that kind of negotiation, which is essential for world peace. Here I'm not talking about the actors. I'm talking about the really fundamental issue of the Iranian nuclear capacity.
To me, there is no contradiction. The problem is that it's very annoying to meet the guy who's doing mischief there. You want to punch him in the nose, but at the same time you still have to smile, and that's what diplomacy is all about. You have to talk to those with whom you have major difficulty because at the end of the day there are some even higher objectives that have to continue to be pursued.
