You are right. We can think about it now, or start thinking when it is too late. To add to that painful list, above, I would ask about our exact dealings with the Iraqi opposition. The greatest set of illassorted ratbags, windbags, bankrupts (literally in some cases) and fundamentalists I have ever seen.
If anyone put in a post, saying I think we should send money to support war criminals and Islamic fundamentalists in the Middle East - there would be an uproar. But that is what we are already doing. No lesson has been learnt by the immoral policy of supporting Sadaam (that is why they had to pull 8,000 pages out of the dossier. They were about the US sending weapons, including anthrax).
