Lots of talk here, but no mention of Sept 11th.
In my view, the West in general had a relatively non-aggressive policy, only intervening to resist aggression from other countries eg Iraq - Kuwait. They have made some serious errors of judgement in the past, of course, and have on many occasions "backed the wrong horse". However, I do not feel that any future civilisation will condemn us for our free and democratic society, or believe that violent or oppressive dictatorships were better.
True, there are lots of double standards, such as there failure to intervene when China invaded Tibet - however, the oil is a factor - politicians have a duty firstly to protect their citizens, then to protect their interests - there is simply no getting away from the fact that oil is crucial to the continuation of our society - not just business, but schools, hospitals, etc, etc.
The US did not have a mandate from the UN to invade Iraq and "finish off" Saddam, hence did not do so. This was also necessary in order not to upset the Arab world. With hindsight it was a mistake, but a mistake made from the best intentions.
Instead, a policy of containment was implemented, assuming that Saddam could do little harm from so far away, and would not ever use the weapons he was known to have.
Sept 11th changed all that, making the west realise that their enemies would stop at nothing to kill and maim them in as large numbers as possible. That is why we now face war.
One important point is to regard the weapons inspectors as auditors - if you have auditors into a company, their job is to identify whether the accounts have been fiddled, not to find the missing cash under someone's bed at their house.
I do not believe the evidence thus far is actually sufficient under normal circumstances, and entirely understand people's reservations. However, I am confident that it remains the right decision, and we will only know after the event the danger we were/are in.
When all is said and done, I do not believe that Tony Blair would involve the UK in such a major war, unless he knew that it was the right thing to do.
