Some very good points there Luke, but I am not sure about point 4.
One of the ways of getting support behind war on Iraq is to persuade all the morons that Saddam is a threat to us, and judging by the (English) people on the news who were asked about it the propaganda is succeeding:
"He's going to kill us so we have to kill him first". Utter nonsense but Dubbya won't be complaining, the vast majority of thick Americans think the same thing.
There is no way Saddam could get the capability to launch a nuclear attack on the UK/USA. The only credible threat is a terror, chemical or 'dirty bomb' attack.
True that oil (therefore economic) interests are the primary factor for America - but they also want Saddam removed for strategic political reasons.
I don't think that the long term plan is to 'sort out' Saudi Arabia however. Even if it were possible I don't see how America could silence the voice of Islam forever (which in their perfect world they would). I'm not at all sure that America does have point 4 on the agenda Luke. The Saudis are an 'ally' of America - remember that they participated in the previous Gulf War on the Allied side. They would still need large amounts of Saudi oil even if the Iraqi supplies became available to them.
Just_Another_PPL - I can't see how a war on Iraq would be positive in any way for wannabes. The price of oil short term would rocket, the public would stop flying again, airlines would go out of business, pilots would be layed off etc etc etc. It's not something wannabes should be supporting for their own selfish reasons.
Whether it should be supported for other reasons, well I am still undecided. America cannot go ahead with the sole support of the UK. But we would all (including the long suffering Iraqi people) like to see Saddam taken out. And I mean taken out properly.
