Accepted Wisdom

Yup. [Link]

It is Accepted Wisdom™ that:

U.S. intelligence told Bush that Saddam tried to buy yellowcake in Niger. Bush claiming to believe that, and repeating it to the American people, was a lie.

And at the same time:

U.S. intelligence told Obama that Russia would not invade Ukraine. You can’t blame Obama for believing U.S. intelligence.
