Let's start with one truth: last March, when the United States and its coalition partners invaded Iraq, the American public and much of the rest of the world believed that after Saddam Hussein's regime sank, a vast flotsam of weapons of mass destruction would bob to the surface. That, of course, has not been the case. In the words of David Kay, the principal adviser to the Iraq Survey Group (ISG), an organization created late last spring to search for prohibited weaponry, "I think all of us who entered Iraq expected the job of actually discovering deployed weapons to be easier than it has turned out to be." Many people are now asking very reasonable questions about why they were misled.
Democrats have typically accused the Bush Administration of exaggerating the threat posed by Iraq in order to justify an unnecessary war. Republicans have typically claimed that the fault lay with the CIA and the rest of the U.S. intelligence community, which they say overestimated the threat from Iraq—a claim that carries the unlikely implication that Bush's team might not have opted for war if it had understood that Saddam was not as dangerous as he seemed.
Both sides appear to be at least partly right. The intelligence community did overestimate the scope and progress of Iraq's WMD programs, although not to the extent that many people believe. The Administration stretched those estimates to make a case not only for going to war but for doing so at once, rather than taking the time to build regional and international support for military action.
This issue has some personal relevance for me. I began my career as a Persian Gulf military analyst at the CIA, where I saw an earlier generation of technical analysts mistakenly conclude that Saddam Hussein was much further away from having a nuclear weapon than the post-Gulf War inspections revealed. I later moved on to the National Security Council, where I served two tours, in 1995-1996 and 1999-2001. During the latter stint the intelligence community convinced me and the rest of the Clinton Administration that Saddam had reconstituted his WMD programs following the withdrawal of the UN inspectors, in 1998, and was only a matter of years away from having a nuclear weapon. In 2002 I wrote a book called The Threatening Storm: The Case for Invading Iraq, in which I argued that because all our other options had failed, the United States would ultimately have to go to war to remove Saddam before he acquired a functioning nuclear weapon. Thus it was with more than a little interest that I pondered the question of why we didn't find in Iraq what we were so certain we would.
