WHO WANTS TO THROW WEIGHTS? By M.L. Verb First, let's admit that Donald Regan, White House chief of staff, is a bozo for saying what he said in Geneva about women. What he said, in case you read only summit stories about the Nancy Reagan- Raisa Gorbachev "Style Wars," was that women "are not going to understand throw-weights or what is happening in Afghanistan or what is happening in human rights. Some women will, but most women. . .would rather read the human-interest stuff of what happened." No question, it was a mindlessly insensitive thing to say, and he deserves the lashing he's gotten. Flail away. Grant him no mercy. And while you're at it, drag in the names of Golda Meir, Indira Ghandi, Margaret Thatcher, Jeane Kirkpatrick and Gerry Ferraro, a collection of your average women. But if you're through flogging him, let's be honest. There was at least SOME truth in what he said. Mr. Regan's error was in thinking that widespread ignorance about the substance of international policy is limited to women. The harsh, frightening truth is it's not just most women who don't understand throw-weights, it's also most men and children. More than that, details of what's really happening in Afghanistan (plus Nicaragua, South Africa, Washington and Moscow) are mysteries not only to common citizens around the world but also to diplomats. Some of what we don't know isn't our fault. Because of the oppressive, paranoid Soviet system, the sorry state of invaded Afghanistan is closed to prying Western eyes. We get only snippets from refugees fleeing in stark terror through Pakistan. And some of what we hear about nuclear arms and throw-weights is so bizarre and unbelievable that we must conclude either no one understands it or people are kidding us. I recall visiting within the past year with a man who occupies a lofty position among U.S. arms negotiators. It was his straight-faced testimony that the most likely date in any year for the Soviets to launch a nuclear attack on the U.S. is Columbus Day. More than that, the risk is greater in either the morning or evening, I can't remember which. If we get through October each year, he said, we're pretty much home free. What can even the brightest among us make of such talk? It is like listening to the crazed predictions of astrologers and palm readers, knowing all the while there is at least some small chance they may be right. The part Mr. Regan got at least a little right, however, has to do with what we CAN know but don't. Our interest in matters of real importance often is distracted by our interest in TV broadcasts of sit-coms, sports or soap operas. How else do you explain the outcry that inevitably comes when news bulletins interrupt taped TV shows? How else do you explain the enormous popularity of magazines like "People," or "Women's Wear Daily" or "Sports Illustrated."? Or TV like "Entertainment Tonight," MTV or "Lifestyles of the Rich and Famous"? Donald Regan is wrong in thinking women are the only ones ignorant about what really affects our lives (but he's far from alone in this old-boy administration). One gender is no less guilty than the other.
