Obviously the WW3 will make look WW2 like a piece of cake.
"Increasing speed of operation marked each new weapons system, particularly the decision-making function (to strike or not to strike, where, how, with what force held in reserve, at what risk, etc.), and this increasing speed also brought the incalculable factor of chance into play. Lightning-fast systems made lightning-fast mistakes. When a fraction of a second determined the safety or destruction of a region, a great metropolis, an industrial complex, or a large fleet, it was impossible to achieve military certainty. One could even say that victory had ceased to be distinguishable from defeat. In a word, the arms race was heading toward a Pyrrhic situation." 1983
