We must be absolutely clear that these are weapons of mass destruction; they are indiscriminate and kill and destroy without grace or favour; and they devastate not just all military targets in their path but all civilians including children, all schools and hospitals, and all livestock and crops.On this point, at least, I agree with the former UK Secretary of State for Defence Des Browne who, writing in The Telegraph on 5 February, said that“large-scale use of nuclear weapons ... would be suicidal”and that“even a small-scale nuclear exchange ... would affect at least a billion people and usher in colder temperatures than at any time in the past millennium.”I also highlight the February 2013 report from the Scottish Campaign for Nuclear Disarmament entitled “If Britain fired Trident—The humanitarian consequences of a nuclear attack by a Trident submarine on Moscow”, which sets out in horrifying detail the devastating humanitarian consequences of a nuclear attack on a large urban area—precisely the type of attack that Trident is designed to deliver.
