Lyric discussion by TimTops 

Given the release date (1982) of the Discharge album this song appears on ('Hear Nothing See Nothing Say Nothing') - and the date of the writing of E. P. Thomson (early 80s), I think this song could well be about mankind's destruction by nuclear war:

From Wikipedia (en.wikipedia.org/wiki/E._P._Thompson):

"From 1980, Thompson was the most prominent intellectual of the revived movement for nuclear disarmament, revered by activists throughout the world. In Britain, his pamphlet "PROTEST AND SURVIVE", a parody on the government leaflet Protect and Survive, played a major role in the revived strength of the Campaign for Nuclear Disarmament."
