Fallout: Conspiracy, Cover-Up, and the Deceitful Case for the Atom BombHardcover, 18 September 2018

The justification for the atomic bomb was simple: it would defeat Hitler and end the Second World War faster, saving lives. The reality was different.

Fallout dismantles the conventional story of why the atom bomb was built. Peter Watson has found new documents showing that long before the Allied bomb was operational, it was clear that Germany had no atomic weapons of its own and was not likely to. The British knew this, but didn't share their knowledge with the Americans, who in turn deceived the British about the extent to which the Soviets had penetrated their plans to build and deploy the bomb.

The dark secret was that the bomb was dropped not to decisively end the war in the Pacific but to warn off Stalin's Russia, still in principle a military ally of the US and Britain. It did not bring a hot war to an abrupt end; instead it set up the terms for a Cold one to begin.

Moreover, none of the scientists recruited to build the bomb had any idea that the purpose of the bomb had been secretly changed and that Russian deterrence was its new objective.

Fallout vividly reveals the story of the unnecessary building of the atomic bomb, the most destructive weapon in the world, and the long-term consequences that are still playing out to this day.
