Well, this is about the UK, but from a US perspective, so I hope that it's not spoiled:

The biggest problem I see with the UK politicaly system now is that Blair doesn't worry about what the UK voters think. He's gone to war under information known now to be known by him then to be false. Against the majority of his own constituency, and the majority of voters in the UK. To please a foreign power. And done it incompetantly. In a better world, he'd have been beheaded for high treason by now. In a somewhat better world, he'd be out of power and living in a foreign country, scared to come back home. In a slightly better world he'd have only held on to power in a coalition with the Liberal Democrats, who'd be exacting a steep price for it, and making him regret hopping into bed with Bush.

However, in the world that we live in, he did all of that, and held onto power with a comfortable margin. Basically, he paid no price of any practical consequence.

So what does he have to worry about what the British people think?
