Publication ABM expert says" missile hit on U.S. worse for Canada ByJOHNDAFOE r Globe and Mail Reporter OTTAWA Canadians would suffer far more from intercontinental ballistic missiles which reached targets in the; northern United States than from missiles which were intercepted above Canada, a Canadian defense expert said yesterday.. Dr. G: R. Lindsey, chief of ,the defense research establishment of the" Department of National Defense, was testifying before hte Commons Committee on External Affairs and National Defense. . He said Canadian territory could be valuable as a site for radar installations for a U.S. anti-ballistic missile system but the question of using Canadian territory in an ABM system has not yet arisen. Dr. Lindsey's presentation was denounced by David Lewis (NDP, York South). "In fact you have tried to make a case for the value of an ABM system," he charged. "No, I didn't try to," replied Dr. Lindsey, a quiet-spoken scientist. "I tried to present a number of facts you would need and give the pros and cons." His paper, however, gave little support to earlier charges by NDP leader T. C. Douglas that the explosion of ABM Spartan missiles over Canada would create a danger of fallout for Canadians below. The Spartan, it noted, is intended to intercept intercontinental ballistic missiles in outer space—at least 25 miles high. At that height, the explosion of a Spartan warhead could break windows on the ground below. On a clear day,it would start some fires in tinder-like material and could cause burns to the exposed skin of persons outside. It would not produce' a dangerous radioactive hazard on the ground., - ' . * "One should not wax too indignant over the hazards inflicted by defensive ABM weapons without contemplating the effects of the offensive ICBM if is should succeed in its intended mission," Dr. Lindsey's paper stated. "Analysis done in CanadaE I indicates that little would be j gained for defense of targets I in the U.S.A. by siting missile ' batteries much to the north of the zones to be defended." Canadian territory could be valuable for the location of radars to warn of ICBM attacks and to track the enemy missiles. "However, no requirement for^ sites in Canada has arisen to date with regard to active defense against ballistic missiles." Dr. Lindsey's paper states that from a strategic point of view, antirbomber and antimissile defense are part of.a single problem, and stiouid be handled together... * ;.^'-" k ;> Anti-bomber defenses are*-' co-ordinated by theU.S.-Cana-' dian North American Air De- 1 fense Command (NORAD) but the agreement specifically states that it does not commit. . Canada to participate in ai #ABM sysem. 1 1 "It is too soon to forecas [what the U.S. view will.be ret Igarding the relationship be- ! Tween NORAD and Safeguard, Quite apart from whether Canada does or does not elect to ., participate in any aspect of active ballistic missile defense." J The...Globe....&.Mail., ICBM attacks'on U.S. mis, ^ : L ••ates in concrete silo$ would involve hundreds of • ground bursts which produce large amounts of 'nuclear fallout. ' , , „ "The nature • of fallout 1 caused by .ground-burst nuclear weapons, and the geography and meteorology of North America, are such tha a series of ground bursts 11 the northern half of th, , U.S.A., particularly in the area of Minuteman bases, is 1 likely to produce heavy fallout j in Canada," the paper k warned. V\ "Consequently, even if Can- 'ada were fortunate enough to escape the impact of nuclear weapons over her own territory, we might still have face the hazards of radioaij tive fallout' due to nuclei weapons burst in the U.S.A. The paper argued that th explosion of an ABM warhead would most likely prevent the ICBM from exploding but noted that some experts think the offensive missile could be programmed to explode when Jhe defensive one did. f "Without judging the merits [of this argument, it will nevertheless be true that, in 'every case, the total damage to North America would be less than would have been suffered if the ICBM had burst where its owners had intended." The significant risks come from an offensive ICBM, and not the defensive ABM, the paper said. "If an ABM prevents an ICBM from bursting at its intended point, both lives and resources have been saved; if it prevents it from bursting on the ground, then the radioactive hazard has been decreased-, to Canada as well as the U.S.A., even if the targets were-all south of the border." 'The Safeguard ABM system proposed by U.S. President (Richard Nixon cannot function [unless its missiles make their. {interceptions over Canada, the 1 [paper noted. The United! bStates, however, has made no] request to place ABM sites J north of the border. 000186 � Text A resource consisting primarily of words for reading.
