If the objective of Sen. John Glenn's article {"Pakistan's Bomb and the Mujaheddin," op-ed, Nov. 4} was merely to castigate Pakistan, then further comment is unnecessary, as he appears to have done a thorough job. If, however, his objective, as I believe it to be, was to address the serious issues of nuclear nonproliferation and of international security, then I may be permitted to submit a modest contribution to the debate.

In the first place, I would categorically refute the four assumptions with regard to Pakistan's nuclear program, which Sen. Glenn quotes on the basis of "reliable news reports," and I would wish to reassert, as I have done before, that our nuclear program is not weapons-oriented, and that we are prepared to accept any form of safeguards that are nondiscriminatory, particularly in the regional context.

It is necessary to recognize, as most realistic political observers have already done, that the purpose of genuine nonproliferation in South Asia can only be accomplished through a regional approach and not by unilateral assaults on the sovereignty of Pakistan. The prime minister of Pakistan, Mohammad Khan Junejo, speaking at the summit meeting of the South Asia Regional Cooperation at Katmandu, Nepal, on Nov. 2, proposed a joint renunciation of the nuclear option as a binding instrument for the countries of the region, and further suggested a regional agreement pledging a comprehensive ban on nuclear testing. These are statesmanlike proposals that combine broad vision with practical measures and characterize Pakistan's approach to this important issue.

So far as Afghanistan is concerned, Pakistan took a position of principle well before the aid package was negotiated with the United States. Under the circumstances, Sen. Glenn's assertion that Pakistan is hostage to the 3 million Afghan refugees who have taken shelter on its soil is a less-than-generous interpretation of events. I can only say that if, during the dark era of European fascism, some of the Western democracies had in their comfortable affluence displayed the same spirit of collective humanitarianism that an impoverished and embattled Pakistan has today demonstrated in absorbing more than 3 million Afghan refugees, then perhaps many lives might have been saved, and there would have been some historical mitigation for that dark era.JU

One final observation: Sen. Glenn, in his charitable wisdom, might be able to overlook India's considerable stockpile of unsafeguarded plutonium. We in Pakistan, unenviably situated in the vicinity of three nuclear states, and having lived since 1974 under the shadow of an Indian nuclear explosion, are necessarily less sanguine.
