Paranoia from the cold war

Britain had secret plans at the height of the cold war to bury nuclear landmines in parts of Germany to thwart a Soviet attack, it emerged yesterday.
The 10 proposed devices would have had the combined explosive power of more than five Nagasaki A-bombs, resulting in craters more than 180 metres (600ft) deep and would have spread radioactive contamination across vast areas of the countryside if detonated.

The weapons, codenamed Blue Peacock, were to be left buried or submerged and detonated by a wire from up to three miles away or by an eight-day clockwork timer.
