2. Saddam Hussein's chemical weapons were well known to America, because American intelligence helped him acquire and target those chemical weapons against Iran in the Iraq-Iran War. Even going so far as to provide him with satellite intelligence for this purpose.
3. The "WMDs" used to justify the invasion of Iraq to the public were not chemical gasses. The US government claimed Iraq had a nuclear weapons program in advanced stages of development. This was never true and they knew it.
I think that the chemical weapons might have been used as an excuse for the first Gulf war by George H.W. Bush, 6 years later ??
Primarily though I think the US govt at the time genuinely thought they could do regime change and create stable democracies in both Afghanistan and Iraq. They doubtless had many murky reasons for wanting to believe they could do this, but I think the belief that they _could_ do it was sincere if proven false by events.
