a distribution postulated is not one which recommends itself for aggressive purposes, For the detection of one or more of the bombs would not merely compromise the success of the entire project but would give the intended victim the clearest and most blatant warning imaginable of what to expect and prepare for. Except for port cities, in which foreign ships are always gathered, a surprise attack by air is by every consideration a handierway of doing the job. VII, oe In relation to the destructive powers of the wean{inca Sasource in raw materials for its production must be considered abundant, . Everything about the atomic bomb is overshadowed by the twin facts that it exists and that its destructive power is fantastically great, Yet within this framework there are a large number of technical questions which mast be answered if our policy decisions are to proceed in anything other than complete darkness, Of first importance are those relating to its availability. The manner in which the bomb was first tested and used and various indica tions contained in the Smyth Report suggest that the atomic bomb cannot be "mass produced" in the usual sense of the term, It is certainly a scarce commodity in the sense in which the economist uses the term "scarcity," and it is bound to remain extremely scarce in relation to the number of TNT or torpex bombs of comparable size which can be produced, To be sure, the bomb is so destructive that even a relatively small number (as compared with other bombs) may prove sufficient to decide a war, especially since there will be no such thing as a "near miss"-~anything near will have all the consequences of a direct hit. However, the scarcity is likely to be sufficiently important to dictate the selection of targets and the circumstances under which the missile is hurled, A rare explosive will not normally be used against targets which are naturally dispersed or easily capable of dispersion, such as ships at sea or isolated industrial plants of no great magnitude, Nor will it be used in types of attack
