-22— \ Apart from the possible irrelevancy for the future of this observation— against which the phrase "at least up to this time" provides only formal protection—the fact is that it is not historically accurate. A casual reading of the history of military technology does, to be sure, encourage such a doctrine. The naval shell gun of 1837, for example, was eventually met with iron armor, and the iron armor in turn provoked the development of the "bujite-up" geun with greater penetrating power; the submarine was countered with the hydrophone and supersonic detector and with depth charges of various types; the bombing airplane accounted for the development of the specialized fighter aircraft, the highly perfected antiaircraft gun, and numerous ancillary devices. So it hasalways been, and the tendency is to argue that so it always will be. | In so far as this doctrine becomes dogma and is applied to the atomic bomb, it becomes the most dangerous kind of sens ER have already seen that the defense against the V-1 was only rélativel eifectiye ; and something approaching much closer to perfect effectiveness would Deaton: necessary for V-1 missiles carrying atomic bombs.
