I am not surprised to learn that Iraq has been found in possession of the weapons the UN inspectors found. I cannot begin to imagine what they would find in any of their neighbours’ back yards: Those people seem to like having those things around.
What has me thinking is this: The weapons were imported (nobody is saying they made them) in the 80’s, but I have seen no reference as to who sold them to Iraq?
What point is the OP trying to make? It doesn’t matter where or how Iraq acquired such items in the mid-eighties. They agreed by treaty to destroy them in 1991.
It may be just an beaurocratic oversight, though. I’m not sure how solid a pretext the discovery is.
They were sold to Iraq (assuming they were not manufactured locally, which they very well could have been) by either USSR (at the time), China, North Korea, Egypt, Syria, or one of many other nations that produces 122mm rocket chemical-delivery warheads.
But France, Germany, America, etc? Nope. None of those used or manufacted 122mm rockets, much less chemical warheads for said rockets.
