As Trump faces down North Korea, it’s alarming to think that most of the world’s nuclear warheads are now in the hands of men who are prepared to use them
The one dropped on Hiroshima measured 15 kilotons; it destroyed everything within 200 yards and burned everybody within 2km. The warhead carried by a Trident missile delivers a reported 455 kilotons of explosive power. Drop one on Bristol and the fireball is 1km wide; third-degree burns affect everybody from Portishead to Keynsham, and everything in a line from the Bristol Channel to the Wash is contaminated with radiation. In this scenario, 169,000 people die immediately and 180,000 need emergency treatment. Given that there are only 101,000 beds in the entire English NHS, you can begin to imagine the apocalyptic scenes for those who survive. (You can model your own scenario here.)
But a Trident missile carries up to eight of these warheads, and military planners might drop them in a pattern around one target, creating a firestorm along the lines that conventional Allied bombing created in Hamburg and Tokyo during the second world war.
What we do know is that Trump has been obsessed since the 80s with nuclear weapons, that he refuses to take advice from military professionals and that he seems not to understand the core Nato concept of nukes as a political deterrent, as opposed to a military superweapon..
This sudden mania for speaking of nuclear warfare, among men with untrammeled power, should be the No 1 item on the news, and the No 1 concern of democratic and peace-loving politicians. See more…
