A TEST-BAN PRIN ER Who called the Geneva test-ban conference? On Aug. 22, 1938 President Eisenhower announced the suspension of U.S. nuclear tests as of Oct. 31. 1985. and invited the U.S.S.R. to a test-ban conference in Geneva. For what reason? The Eisenhower Administration conceived a test-ban treaty as a possible step toward controlled general disarmament. In 1953-37. When Russian propagandists were clamoring for a ban, resident Eisenhower insisted chat he would negotiate one only as a part of a larger package. including a of the Geneva Conference. As far as the U.S. knows. the U.S.S.R. has not done any Would the stopping of U.S. underground tests hamper development and What would the U.S. gain from a test-ban agreement? The warheads designed for the Polar! and Minuteman solid-tuel missiles. which the U.S. is depending upon to close the missile gap in the mid-ty6os. pack a nuclear punch of about hali a megaton, compared with an estimated eight megatons testing since then, The stopping of all above-ground tests by Russia and Britain (as well as the U.S.. of course) and perhaps some progress toward making outer space off limits for nuclear shots. President: Eisenhower and Secretary Herter also believe that it would be good to get the nuclear rules set up before other nations begin to manu- facture nuclear weapons. Would a nuclear treaty have to be halt in production of nuclear materials approved by the U.S. Senate? ward disarmament. Would the U.S. lose any of its present bombs bythe treaty? for weapons purposes, and other steps to- Why is the U.S. now discussing a ban apart from disarmament? President Eisenhower and Secretary of State Herter hope that a test-ban treaty will be a “first step” toward disarmament. One of the biggest obstacles to any dis- armament agreement with Ruszia is an al- most paranoid Soviet wariness toward Western inspection and contrat proposals. Eisenhower and Herter think that if a test-ban control system could be negotiated with the Russians. it might be a “breakthrough” on disarmament control problems. When did the U.S. stop nuclear tests? On Oct. 30. at the end of the Hardtack test series in Nevada. The series included three underground tests of various sizes. Did the U.S.S.R. also suspend nuclear testing? Yes. by a two-thirds majority No. How many bombs does the U.S. have? The numberis classified. but the U.S. does have a widely diversified and dependable ‘‘family” of bombs and warheads. These range from small. low-vield. lightweight weapons used by ground and naval forces to the big H-bombs carried ‘by B-52s. Furthermore, there are nuclear de- vices for antisubmarine warfare, antiaircraft. air-to-air missiles and interconti- nental missiles. Do the bombs and warheads deteriorate? No, they need maintenance but they remain lethal. Is the U.S. supply enough to obliterate Russia? Manytimes over. Would the treaty banning above. Not right away.

It is generally conceded that the U.S. ge es ome aerate woes « ‘ og € ‘ carried by Soviet intercontinental bailis- tic missiles. and about three or four m we tons in the nose cone of the U.S.’s Acias ICBM. With additional nuclear tests. the yield of the Polaris and Minuteman warheads could be significantly increased. although Adniiral William Raborn Jr. nas said he needs no further tests of the present Polaris warhead. Some U.S. scientisis and military men would like further testing to develop “clean” nuclear weapons wita little fallout. The U.S. has developed small warheads, with a yield of less than one kiloton.* for use in tactical weapons. but so far these small warheads are “dirty.” and the dirtiness makes it dif- ficult for troops to follow behind the bombardmient. Would a halt in development of tactical nuclear weapons impair U.S. defense? Some military experts think so. even if the U.S.S.R. did not evade the ban by carrying out clandestine tests. Develop- ment of tactical nuclear weapons making it possible for the U.S. to overcome Coammunist superiority in military manpower without resorting to mass-destruction Hbombs, has long been a hope and geal of U.S. military thinking. Former Atomic Energy Commissioner Thomas E. Murray argues that the only way the U.S. can escape from the “balance of terror” is to shift from reliance on mass-destruction H-bombs to reliance on tactical nuclear weapons. A test ban, he development of such weapons. Many earnest otherwise be willing to says. would stop tactical nuclear men who might go along with a test ban are haunted by the possibility that the U.S.S.R. would find wav: to evade the ban and develop nuclear weapons superior to the U.S.'s. To guard against this possibility. the U.S. has insisted from the outset that anv nuclear test-ban agreement must include an adequate system of detection and control. » le Som, em 7 . q - $8244 uaivizoss¥ US.
