Opinion is one thing, beardedbruce, facts are another. You can have an opinion on whether or not the US was justified in violating the UN resolution, but the language of the resolution itself is quite clear in what it does and does not do, what it does or does not authorize, and what would constitute "act(ing) in accordance with (the) resolution". The resolution quite clearly states that it's purpose was to establish and to enforce UN inspections in Iraq. Those inspecions were ongoing (meaning that the UN was enforcing its resolution) at the time that the US kicked the UN inspectors out of Iraq (thus violating the resolution) just prior to invading Iraq (another violation of the very specificly worded resolution).
