From Mel Tisdale
The problems currently being experienced by the Trident nuclear warhead programme (8 March, p 15) provide an excellent opportunity for a step towards eventual nuclear disarmament.
Instead of trying to make them operate as thermonuclear or hydrogen bombs, why not limit them to less-destructive fission or atom bombs only? The ability to destroy any target to the extent that Hiroshima and Nagasaki were destroyed ought to be more than enough.
