Well now you have to go all silly. We knew he had WMD because we gave it to him, or rather we, the western allied, sold it to him back in the 80's. He was considered the second worst possible ally between Iraq and Iran.....When pappa Bush launch his war we discovered that Saddam had secretly been refining Uranium. He was able to acquire that technology because of the support we gave him including export licensing of duel use technology by US firms and our European allies. He was an attack dog who got rabies and tried to bite his master. He got put down like rabid dogs do.
Sorry. Iraq was crippled by 2 decades of war and sanctions. They had no WMDs. This was all about clean Break Strategy. Operation Mass Appeal was launched in the UK in a massive propaganda effort lead by sir Derek Plumbly after his total fuck up with the November 2000 booze wars in Arabia.
They were setting the Palestinians up to take the blame, but when they started blowing up other Brits they got caught.
