It is fair to say that although that treaty has particular resonance in Europe, a number of other treaties have come into place since then. There has been a new strategic arms reduction treaty, and constant discussions are taking place to try to secure non-proliferation. The treaty is clearly important in its own terms, but it is a treaty signed between two countries. We would like one of those two countries, which is clearly in breach of it, to come back to the table. Only when that happens can we be sure that the stability that came into place at the signing of the treaty 31 years ago will be maintained.
