Yes, all of us in the West, and Russia, helped Saddam develop WMD
There’s a ton of information on this web site about Iraq’s history of WMD, analysis of UN inspections, etc.!
It was mostly the greed of German and French companies, but also involved were Spain, Italy, Switzerland, Russia, the UK and the United States (and many others)…
But apparently it’s only the US, the UK, and a few others in the coalition who are doing the right thing by stepping in to disarm Saddam and clean up the mess.
