The Post's story is also discussed on the BBC website. Under the headline "Wanted: an Iraqi link to al-Qaida ",
Paul Reynolds, the website's world affairs correspondent, views it as part of a long and unsuccessful effort to link Iraq with al-Qaida.
"One of the most intriguing questions in the 'war on terrorism'," he writes, "is whether there are contacts between Iraqi leader Saddam Hussein and Osama Bin Laden's al-Qaida network. Intelligence agencies are constantly looking for the 'missing link'."
The quotation marks around "missing link" distance the BBC from the idea that such a link exists, though the definite article preceding it suggests otherwise. Why are intelligence agencies looking for "the" missing link and not "a" missing link?
Journalistically, it's more interesting to talk about a "missing" link than a "possible" link but even when the tone of discussion is sceptical - as it was in the BBC's case - there's still a drip effect. The more we mention missing links, the more people will assume they are out there somewhere, waiting to be found.
