My Lords, we have been speaking to both Washington and Moscow about the anti-ballistic missile treaty and the need for an agreement. We have been encouraging both sides to negotiate so that an amendment to that treaty will be possible. The treaty has been amended in the past; it is possible for it to be amended again. We are very hopeful that our Russian and American colleagues will take this matter seriously and resolve it between them. We are not a party to that treaty, but we obviously wish them well in coming to some accommodation.
