Hussein bragged about what he'd do if the US attacked (Chem-bio I think), not to mention his refusal to comply with UN Resolutions for nearly 13 years.<quoted text>
Learning of the truth and when we learned was was controversial. Still is. I personally find it hard to believe we didnt know and base that belief on our ability and resources to gather and analyze data, even back in 03
Regarding Husseins regime and family, are you implying we didnt have that intel before the invasion of Iraq? Im guessing thats not what you meant to say.
Since we're not privvy to WH meetings, there's no way to be sure of
what the US knew and when (other than the written reports submitted well after the event). Hussein knew the UN inspectors were coming and had several months to move things around in a sandbox the size of Texas. Also Hans Blix was a known dove and had limited interest in actually finding WMDs in Iraq.
The US probably had cursory intel regarding the oppressive regime, but not likely the depth of depravity, abuse and cold blooded murder. IIRC, some Iraqis produced cell phone videos of the abuse, beatings, etc., for reasons only a madman and his henchmen could dream up.
