Jay Davis\, who served as an UNS COM inspector in Iraq after the first Gulf War and as the head of all US inspection processes as first Director of the Defense Threat Reduct ion Agency\, recently lead an APS/POPA study on the technology needs f or future arms control treaties. However\, in addition to technology\ , many other issues matter as the number of nuclear weapons is decreas ed. Among these are changes to theories of deterrence and the nuclear umbrella over non-nuclear states\, the lesser granularity of military platforms that support the weapons\, increased credibility of missile defensive systems\, and the coupling of conventional and nuclear weap ons\, among others. Davis will walk the audience through a progressiv e set of weapons reductions that illustrate these points. Comparison to either Zeno's Paradox or Dante's Circles is discouraged. The talk does however end with an interesting technical proposal for evaluation . URL:https://www.physics.wisc.edu/events/?id=1944 END:VEVENT END:VCALENDAR
