 Colonel L Buckley, then Director of Intelligence briefed Peter Barry, then foreign minister, in November 1983 on the possibility of British/NATO nuclear missiles on the island of Ireland.Col Buckley believed nuclear weapons could be situated at underground facilities inside Benbradagh mountain in Derry, which US forces used as a communications hub in order to communicate with its North Atlantic fleet, but which were also designed for the storage of conventional high explosives.Col Buckley complained that he did not have "the monitoring or surveillance systems" to confirm the presence of nuclear weapons in Northern Ireland, but that the British strongly denied land-based systems in the territory and refused to confirm the movements of air and sea based nuclear weapons.
