As this is being written, the Korean war is just one month old. By the time these lines appear in print we may know whether the naked Communist aggression on the Republic of South Korea was an episode, a prelude, or the first act of World War III. But whatever history records, the first flash of the Communist guns, supplied by the Kremlin, has revealed to the free world at last the face of the enemy in all its hideousness. It brought the first phase of the so-called cold war to a definite end. It aroused freedom-loving peoples everywhere and put them on the alert. It served as a powerful headlight in the night, revealing many dangerous curves on the road ahead. It has given the United Nations its first great opportunity to display its vitality for all the world to see. Among other things, the flash of the North Korean guns has illumined for us more clearly than ever before the path we must follow in our policy on atomic weapons, both the A-bomb and the H-bomb. It has revealed the extreme danger lurking in any plan to outlaw production and use of atomic weapons in a world constantly threatened by a savage dictatorship, ready to pounce on it at the first sign of weakening in its armor. The flash of the Red guns, in the first place, made it clear to free men everywhere that to renounce our right to the production of atomic weapons as potentially the greatest deterrents against the further spread of Communist aggression, and as the most powerful defenders of the spiritual and moral values without which our way of life would become meaningless, would allow the Red Army to overrun what remains of the free world. Such a move on our part, for the present and the foreseeable future, may herald the last appearance of free men on the stage of history. It would be, as the Goncourt brothers feared, “closing time, gentlemen!” In addition to warning us what we must not do, the Red guns also gave warning of a more positive nature. They warned us to make all haste in the construction of the hydrogen bomb, to get it ready as soon as possible, against the eventuality that Russia may decide it would be to her advantage to precipitate World War III before our H-bomb is ready. Instead of the estimated pre-Korea time-table of three years, it now becomes a vital necessity for us to complete our H-bomb, and facilities for its production at a speedy rate, within a year. And if the history of our development of the A-bomb may serve as an example, it almost becomes a certainty that we shall do so. While we may not announce it to the world, we have good reason to expect that the first H-bomb will be ready for testing sometime in 1951, possibly in early summer.
