HL Deb 13 March 1986 vol 472 c786WA
Lord Kennet

asked Her Majesty's Government:

Whether they consider an experiment in which a laser beam weapon is used against a ballistic missile in flight would constitute a "test" of the kind precluded under the ABM Treaty of 1972 (strictly interpreted), if conducted by either the Soviet Union or the United States.

The Minister of State, Foreign and Commonwealth Office (Baroness Young)

It is not for us to determine whether any specific activity by parties to a treaty to which we are not a party is or is not in accordance with it. I would only refer the noble Lord to Article IV and Common Understanding B of the ABM Treaty, together with Annex B to the April 1985 US Department of Defense report to Congress, a copy of which I placed in the Library of the House on 24th October 1985.
