A lot of rational people in the US look at what's happening in Iran, and ask, "didn't we learn a lesson with the Iraq invasion?"
And the answer is not "no". We did learn a lesson. We learned that people who are ostensibly liberal and disastrously wrong (Jon Chait, Yglesias, etc, all of whom supported war in Iraq) can make a shit ton of money, despite being doofuses who were wrong
Judith Miller was the Bush admin's biggest propagandist at the NYT, and she got book deals out of it!
