Yes I understand how Sadam got hold of the weapons and to be fair I did use the caveate: "or at least when the bloated bodies turned up on the BBC". Whatever the wests true motives, those reports put a huge amount of pressure on the west to drop their military support, which they did like the proverbial hot potato.
Was the public outrage against the west's support diliberately triggered by the west themselves as a convienient excuse to isolate him for other reasons? - Occam's razor says no, the west simply underestimated him and didn't expect him to use the weapons in the glare of the press and on that particular group, but you, occam and I don't know, and probably never will.
That sort of machevelian shit hasn't stopped, since Hamas won the palestinian election* by a landslide 70% the US has been supplying arms to Fatah (Arrafat's group and Hamas' political rivals). It's was kind of amazing to see Powel walk into Arrafat's bunker when it was under siege by the IDF, not so amazing to see Arrafat pass away shortly afterwards, I would have liked to have been a fly on the wall for that meeting.
Palestinian election* - Rightly demended by the west as a step in the 'peace process" and independently judged by international observers as "free and fair". Arrafat procrastinated about having one for way too long, but when he was 'out of the way' the silly palestinians screwed everything up by voting for the 'wrong team'. The west instantaneously reacted by abandoning any pretense of democratic principle, they isolated them even further from the international economy and bombed the fuck out of Lebannon (again). This was despite the fact that Hamas demonstrated they had enough control over their forces to stop all rocket attacks for almost 2yrs (another step in the so called process).
Predictably the US media in particular took the 'moral highground' and made a lot of noise about the words "right to exist' while at the same time convieniently ignoring the actual deeds that were happening on the ground, which is the exact opposite of what the BBC did back in the 80's on the supply and use of the gas(you may recall it was also smeared and attacked by all sides for doing the same thing in the run up to the latest Iraq war, Al Jazeera was doing it when they were 'accidently' bombed). /rant
Disclaimer: I have no time for grand conspiracy theories where simpler group think explainations suffice. The above rant about hamas is not support for hamas or a political conspiracy, It is IMHO support for a principled democracy and evidence that all sides have people who are willing to compromise, and all sides have people who are willing to go to war to stop that from happening, These opposing personalities are in all of us and they present themselves when-and-where ever we 'draw a line' under the amount we are willing to compromise. Ultimately results on the ground are what count, and with 20/20 hindsight the results of compromising with a ruthless dictator by taking him off that WMD blacklist should have been obvious to all concerend, the real problem is that very few were concerned until the obvious occured.
