I’m not so sure I get it. How does he mean the media was so wrong about WMD? I assume he is looting to Iraq and how are the media kept claiming there wasn’t any and we really did find some but if it’s the other way around then I’m not sure I buy the whole thing.
I believe he is saying that the media immediately believed Blair and Bush when they said there were major WMD in Iraq, as a justiication for the war there, when in fact very few were found. The left questioned whether there was enough there to justify the war there; and even the right is now coming to see that the Iraq war may have been one of our biggest mistakes, and certainly many wasted lives and expenditures.
He is a bit of a lefty, so his opinion may be oriented more to the left; but the main thrust of his article is the complete lack of journalistic standards today, tracing back to the embarrassment of the press initially "buying" the WMD story instead of waiting for more facts. His comments and criticisms of the media's handiling of the Russiagate thing are very condemnatory—and what a great writer! One pithy or hilarious comment after another.
