I don't think anyone is denying the gravity of the situation. Personally, I have a real moral objection to violence, and don't believe in "an eye for an eye". Having said that, I'm afraid there's really not that much in the way of alternatives. The Taliban are not a very nice organisation and the world needs them about as much as we need the IRA, BNP et all. I guess, if we must have a war then it needs to be focused specifically on the terrorists, even accidental co-latteral damage is wrong. What worries me is mankind's capacity to demonise a percieved enemy, i.e. A lot of people think the entire Arab world is prepared to fight to the death, when in reality it's a slack handfull of fanatics.
The most worrying thing is that our leading politicians all seem more than willing to fan the flames for their own political gain. Just look at Tony Blair - You'd think he was running for election as Prime Minister of Earth.
