START III
START III was a proposed bilateral arms control treaty between the United States and Russia that was meant to reduce the deployed nuclear weapons arsenals of both countries drastically and to continue the weapons reduction efforts that had taken place in the START I and START II negotiations. The framework for negotiations of the treaty began with talks in Helsinki between US president Bill Clinton and Russian president Boris Yeltsin in 1997. However, negotiations broke down, and the treaty was never signed.
Proposed basic elements of the treaty included:
- By December 31, 2007, coterminous with START II, the US and Russia would each deploy no more than 2,000 to 2,500 strategic nuclear warheads on intercontinental ballistic missiles, submarine-launched ballistic missiles, and heavy bombers. Russian officials stated that they were willing to consider negotiated levels as low as 1,500 strategic nuclear warheads within the context of a START III agreement.
- The US and Russia would negotiate measures relating to the transparency of strategic nuclear warhead inventories and the destruction of strategic nuclear warheads as well as other jointly agreed technical and organizational measures to promote the irreversibility of deep reductions.
Very little progress was made towards completing negotiations on START III. Attempts at negotiating START III were eventually abandoned, and the US and Russia instead agreed to the Strategic Offensive Reductions Treaty or Moscow Treaty.
