Instead, the NYT wrote an article about how dangerous Saddam's WMDs were and how he was supporting terrorism, even though it had nothing to do with 9/11. Nowadays they defend themselves by saying "everyone agreed at the time". It's not true.
Mainstream media is a rubber stamp for corporate and state interests, just propaganda. They rubber stamped Bush's war's just like they rubber stamped Obamas, they will probably rubber stamp Trump's too. Yes, they also contain true information, but they are still just corporate/state propaganda.
If they aren't willing to fact-check the govt for an issue as serious as going to war, especially with all the red-flags that were out there, like the fact that Colin Powell, a year prior to holding up anthrax in congress as "proof" that Iraq had WMDs, was giving speeches a year earlier claiming there was no evidence Saddam was making WMDs. Like the fact the Bush admin certainty about WMD was far greater than the actual intel communities claims. No one fact-checked them.
And, by the way, the NYT fired the reporter and an editor over that mistake, wrote numerous articles on how it happened, and instituted new rules to prevent similar things happening in the future.
