moondog - real life experiences would include actually having first hand experience of a war.
Intelligent, honourable, rational people who have seen the devastation and loss of life caused by war tend not to talk out of their back sides when it comes down to making decisions about starting wars, esp. when the war is against international law.
The last time Bush and Blair and their families were involved in a real war was when they played a computer game called "Let's bomb those F*ing Ayrabs [sic] - any Ayrabs even those not directly involved in 9/11"
I haven't got a clue what Kember is like as a person or why he went to Iraq. But I tend to have more sympathy for people who despise wars. It is none of my business or any one else why he is a peace activist. If that is what he wants to do with his life, let him do it.
As for putting soldiers' lives in danger. That is a very very silly argument. I think you need to be questioning Bush, Blair at al as to how they can justify murdering thousands of women and children in Iraq and putting the lives of British/US soldiers at risk.
You are questioning the motives of the wrong people.
