Just watched the Porton Down programme ont telly.
Very surprised how close we had come to MAD in WW2.
Knew about the anthrax experiment, but only learned by this programme that the Anthrax bomb was actually produced. Not used, but questionably that is more by luck than by judgement.
That would have annihilated the population of Central Europe, both friend and foe.
The Nazi would probably have retaliated with Sarin, which at the time the allies knew nothing about.
So, that in turn would have annihilated the UK.
