This is from a recent article in which a generally left wing British commentator admits he was very, very wrong to support the war in Iraq:
The lamest defence I could offer – one used by many supporters of the war as they slam into reverse gear – is that I still support the principle of invasion, it’s just the Bush administration screwed it up. But as one anti-war friend snapped at me when I mooted this argument, “Yeah, who would ever have thought that supporting George Bush in the illegal invasion of an Arab country would go wrong?” She’s right: the truth is that there was no pure Platonic ideal of The Perfect Invasion to support, no abstract idea we lent our names to. There was only Bush, with his cluster bombs, depleted uranium, IMF-ed up economic model, bogus rationale and unmistakable stench of petrol, offering his war, his way. (Expecting Tony Blair to use his influence was, it is now clear, a delusion, as he refuses to even frontally condemn the American torture camp at Guantanomo Bay).
