Follow the Uranium

By FRANK RICH
Published: July 17, 2005

WELL, of course, Karl Rove did it. He may not have violated the Intelligence Identities Protection Act of 1982, with its high threshold of criminality for outing a covert agent, but there's no doubt he trashed Joseph Wilson and Valerie Plame. We know this not only because of Matt Cooper's e-mail, but also because of Mr. Rove's own history. Trashing is in his nature, and bad things happen, usually through under-the-radar whispers, to decent people (and their wives) who get in his way. In the 2000 South Carolina primary, John McCain's wife, Cindy, was rumored to be a drug addict (and Senator McCain was rumored to be mentally unstable). In the 1994 Texas governor's race, Ann Richards found herself rumored to be a lesbian. The implication that Mr. Wilson was a John Kerry-ish girlie man beholden to his wife for his meal ticket is of a thematic piece with previous mud splattered on Rove political adversaries. The difference is that this time Mr. Rove got caught.

KEY QUOTES

"To see the main plot, you must sweep away the subplots..."

"These attacks, too, are red herrings. Let me reiterate: This case is not about Joseph Wilson."

"This case is about Iraq, not Niger. The real victims are the American people, not the Wilsons. The real culprit - the big enchilada, to borrow a 1973 John Ehrlichman phrase from the Nixon tapes - is not Mr. Rove but the gang that sent American sons and daughters to war on trumped-up grounds and in so doing diverted finite resources, human and otherwise, from fighting the terrorists who attacked us on 9/11."

"That's why the stakes are so high: this scandal is about the unmasking of an ill-conceived war, not the unmasking of a C.I.A. operative who posed for Vanity Fair."

"Once we were locked into the war, and no W.M.D.'s could be found, the original plot line was dropped with an alacrity that recalled the 'Never mind!' with which Gilda Radner's Emily Litella used to end her misinformed Weekend Update commentaries on 'Saturday Night Live.' The administration began its dog-ate-my-homework cover-up, asserting that the various warning signs about the uranium claims were lost "in the bowels" of the bureaucracy or that it was all the C.I.A.'s fault or that it didn't matter anyway, because there were new, retroactive rationales to justify the war. But the administration knows how guilty it is. That's why it has so quickly trashed any insider who contradicts its story line about how we got to Iraq, starting with the former Treasury secretary Paul O'Neill and the former counterterrorism czar Richard Clarke"

"Next to White House courtiers of their rank, Mr. Wilson is at most a Rosencrantz or Guildenstern. The brief against the administration's drumbeat for war would be just as damning if he'd never gone to Africa. But by overreacting in panic to his single Op-Ed piece of two years ago, the White House has opened a Pandora's box it can't slam shut. Seasoned audiences of presidential scandal know that there's only one certainty ahead: the timing of a Karl Rove resignation. As always in this genre, the knight takes the fall at exactly that moment when it's essential to protect the king."
