Ok, I'm reading between the lines a bit, but not by much. George Will doesn't only criticize the Bush administration overall, he also seems to be implying that Rumsfeld should realize he's not indispensable and that his legacy would be better served by his resigning now. See what you think:
When there is no penalty for failure, failures proliferate. Leave aside the question of who or what failed before Sept. 11, 2001. But who lost his or her job because the president's 2003 State of the Union address gave currency to a fraud -- the story of Iraq's attempting to buy uranium in Niger? Or because the primary and only sufficient reason for waging preemptive war -- weapons of mass destruction -- was largely spurious? Or because postwar planning, from failure to anticipate the initial looting to today's insufficient force levels, has been botched? Failures are multiplying because of choices for which no one seems accountable....
Are the nation's efforts in the deepening global war -- the world is more menacing than it was a year ago -- helped or hindered by Rumsfeld's continuation as the appointed American most conspicuously identified with the conduct of the war? This is not a simple call. But being experienced, he will know how to make the call. Being honorable, he will so do.
He knows his Macbeth and will recognize the framing of the second question: Were he to resign, would discerning people say that nothing in his public life became him like the leaving of it?
This nation has always needed an ethic about the resignation of public officials. Such an ethic cannot be codified. It must grow in controlling power from precedent to precedent, as an unwritten common law, distilled from the behavior of uncommonly honorable men and women who understand the stakes. A nation, especially one doing the business of empire, needs high officials to be highly attentive to what is done in their departments -- attentive far down the chain of command, as though their very jobs depended on it.
Finally, the second axiom. It is from Charles de Gaulle: The graveyards are full of indispensable men.
