With a smile, he went right to it.
He tackled a job that couldn't be done,
And couldn't do it.

WASHINGTON -- In 1969 President Nixon appointed a former congressman named Donald Rumsfeld, then a stripling of 36, to head the Office of Economic Opportunity, an agency devoted to the task of eliminating poverty in America. Rumsfeld returned home late one night to find that his wife Joyce had taped the above doggerel to the refrigerator door. If you wonder why Rumsfeld, now 71, is not discouraged by the problems of postwar Iraq, remember he headed Nixon's Cost of Living Council, an absurdity devoted to the impossible -- administering wage and price controls. Over the years he has had really difficult jobs -- jobs about which he could have, and may have, produced memos every bit as sobering as his ``long, hard slog" memo about Iraq, which surfaced this week and caused much feigned excitement among the very war critics who have hitherto complained that Rumsfeld is incapable of seeing the dark side of things.

In our time, only George Shultz (the first director of the Office of Management and Budget, secretary of labor, then treasury, then state) and Pat Moynihan (assistant secretary of labor, White House domestic policy adviser, U.S. representative to the United Nations, ambassador to India, four-term senator) have had public careers with the breadth of Rumsfeld's (member of Congress, ambassador to NATO, White House chief of staff, special envoy to the Middle East, twice secretary of defense).

Like Saul Bellow's Augie March, Rumsfeld is ``an American, Chicago born,'' and Midge Decter, in her just-published biographical essay ``Rumsfeld: A Personal Portrait,'' correctly says he is still not a Washingtonian, but remains a ``child of that prairie-driven culture of vitality.'' However, no one knows more about Washington's ways. And last Saturday afternoon, in a hushed Pentagon where the escalators are turned off on weekends -- and you thought government is not frugal -- Rumsfeld, wearing a fleece vest and feeling feisty, reflected on current controversies.

He argues that although certainty is desirable when making policy, there also is one of Rumsfeld's axioms: ``A narrow focus on the certain obscures the almost-certain.'' Critics contend, correctly, that six months of postwar access to Iraq reveal more uncertainties than anyone imagined in prewar intelligence. However, in the realm of shadows and mirrors that is intelligence from secretive societies, certainty is a luxury policy-makers often cannot wait for.

How much certainty is requisite as a basis for action depends in part on the consequences of being wrong. If, Rumsfeld says, the Iraqi regime had been less wicked, or if it had been in pursuit of the military equivalent of ``a BB gun,'' the United States, even in the post-Sept. 11 environment, could have afforded to give the regime the benefit of more doubts. And could have been more relaxed about classifying matters as ``doubts.'' Continued...
