Global nuclear war would terminate human civilisation
Any reasonable examination of the consequences of a global nuclear war, must conclude that It would mean the end of human civilisation, and possibly mankind as a species.
Medical services would be totally overwhelmed by the needs created by even a single nuclear weapon, let alone the thousands that would be used in a global nuclear war. Health workers would be inundated by a tsunami of crush injuries, trauma, radiation sickness, and infections at a time when the supply of dressings, fluids, hospitals, transport, communications, and pharmaceuticals would have been reduced to nothing.
Worst of all, even the uninjured would be existing in a world darkened by “Nuclear Winter” caused by tonnes of soot and smoke sent into the atmosphere by the nuclear detonations. The darkness and cold caused by this layer would cause crop failures for many years. Along with dwindling supplies of food and clean water, and with armed, desperate gangs ready to take any food they could find, the idea of surviving a nuclear war is nothing but a delusion.
