On September 16, 2010, a major step was accomplished on the START ratification. After five months of intense negotiations, the US Senate Committee on Foreign Relations approved the US-Russia agreement on strategic nuclear weapons reduction with a large bipartisan majority (14 – 4). The main concerns expressed during the Committee hearings were the relation between the START Treaty and the US missile defense system in Europe; the Obama Administration financial commitment to modernize the national military nuclear infrastructure and the question of Russian tactical nuclear weapons.
