-36- | added that the ‘only form of defense that offers any security whatever" falls far short, even without any consideration of rockets, of offering the already qualified kind of security it formerly offered. V. Superiority in numbers of bombs is not in itself a guarantee of strategic Superiority in atomic bomb warfare. Under the technical conditions apparently prevailing today, and presumably likely to continue for some time to come, the primary targets for the atomic bomb will be cities, One does not shoot rabbits with elephant guns, especially if there are elephants available. The critical mass conditions to which the “bomb is inherently subject place the miminum of destructive energy of the individual unit at far too high a level to warrant its use against any target where enemy strength is not already densely concentrated. Indeed, there is little inducement to the attacker to seek any other kind of target, If one side can eliminate the cities of the other, it enjoys an advantage which is practically tantamount to final victory, provided almaysits ovm cities are not similarly Pal eliminated, is s a7 Be ay <= The fact that the bomb is inevitably,.a weapon of indiscriminate destruction will carry no weight in any war in which it is used. Even in World War II, in which the bombs used could to a large extent isolate industrial targets from residential districts within an urban area, the distinctions imposed oy international law between "military" and "non-military" targets disintegrated entirely, 25. How large a city has to be to provide a suitable target for the atomic 256 This was due in part to deliberate intention, legally permitted on the Allied Side under the principle of retaliation, and in part to a desire of the respective belligerents to maximize the effectiveness of the air forces available to them, "Precision bombing" was always a misnomer, though some selectivity of targets was possible in good weather. However, such weather occurred in Europe considerably less than half the time, and if the strategic air forces were not to be entirely grounded during the remaining time they were obliged to resort to "area bombing," Radar, when used, was far from being a substitute for the human eye, .
