Yes, especially in light of what's happening on the Korean peninsula, and especially if you consider the fact that we have worsening tensions with Russia. In the past that has been an area where some headway was made in terms of mutually reducing nuclear stockpiles and so on. That's an area that has to be considered. I know it sounds counterintuitive because of the nature of the geopolitical situation right now, but I think that could be seen as a way to reduce tensions over the long term by finding one area where you can achieve some common ground.
I think there's a growing acceptance that, in light of what's happening in North Korea, the proliferation of nuclear weapons is one of the most profound security threats to the planet.
