"Not so long ago it was possible to take some little comfort from the idea that the clash, if it came, could perhaps be settled by what were called "conventional weapons"-bombs, tanks, cannon and men. Today that little grain of comfort is denied us for it has been made clear that the weapons of ultimate horror will certainly be used, and the military planning of nations is on that basis. The unconventional has become the conventional, and who knows what other examples of misguided and diabolical scientific skill have been discovered as a plague on humanity."
