Polybore has changed one's mind about the invasion of Iraq. It is very important that the justification for this war is sorted out, in respect for those thousands who have lost their lives and those who will bear the scars for the rest of their lives.
When the war started it was pretty obvious that the weapons of mass destruction argument for invading was a false one. This has been borne out by the failure to find any significant evidence of WMD in the years following the invasion. It was also evident that the invasion would cause chaos and anarchy in Iraq, there have been plenty of lessons from history demonstrating what happens to a country after invasion.
The new reason justifying the invasion of Iraq after a bit of Orwellian rewriting of history is the removal of Saddam Hussein. This argument does not wash either, how can you justify removing one dictator when you allow others to stay in power like Mr Mugabe of Zimbabwe.
Of course the elephant in the room is Iraq's oil resources. Why can't the US and UK just come out and say this was the reason for the Iraq War? It is the one justification that will stand the test of time. Invading Iraq to secure the oil resources was a good idea, look at the oil price just now, imagine what it would be if Saddam Hussein was still in power.
How can war be justified for oil? Look at the effects high oil price are having, a world food shortage is developing that could result in the deaths of millions of people. If Saddam were still in power, with the ever present threat of war, the price of oil would be far higher.
