US President Barack Obama, speaking at Washington’s two-day nuclear summit, said that Russia’s $2.5 billion plan to close the last of its plutonium-based civil reactors ‘demonstrate[s] Russia’s leadership on nuclear security issues‘ (click for video). The summit also saw Ukraine agree to get rid of its stockpile of weapons-grade uranium.  President Dmitry Medvedev offered several soundbites during his US visit: Russia needs several decades to develop effective political and economic systems; Kyrgystan is on the verge of possible civil war and could become ‘a second Afghanistan‘; claims that Stalinism is on the rise are exaggerations; Russia is counting on the US to support its entry to the World Trade Organization, which should be swift and ‘without humiliation‘.  Medvedev also said that he would ‘push as hard as I can‘ on a new sanctions regime against Iran.  The provisional government of Kyrgyzstan is meeting officials for talks in Moscow today.  ‘Kyrgyzstan is much more important for US-Russian relations than arms control, which is an agenda of the past,‘ suggested a US editor.
