Last week, the Russian government took the highly unusual decision to publish two draft treaties, complete with articles and formal legalistic language, on European security — one between Russia and NATO, one between Russia and the United States. During my five years in the Obama administration, I often participated in talks with the Russians on major agreements, including two that we succeeded in completing, the New START Treaty and Russia’s accession agreement to the World Trade Organization. In those serious negotiations, Moscow never started by issuing a list of demands.
