If those imams are preaching "death to the West", then I'm not sure that Britain's support of the war in Iraq would have made that much difference. I suspect that regardless of whether or not Britain supported the war in Iraq, that this type of attack would have occurred sooner or later. Maybe I'm way off here, but the isalmocrazies hate the West just because. I think Britain was in for it eventually no matter what.
My first suggestion is that they do not allow the Imams to go to Trafalgar Sq and celebrate on 911 like they did on the one year anniversary.
Sure, you're very likely right. I think Iraq might have been involved in the radicalisation of the bombers, but equally so could their potty training as children.
The critical factor is their probable brainwashing by what sounds much like any other destructive cult, like Aum Shinko, the People's Temple or even the Manson family.
That's why it's important to focus on the cult leaders, without them you've just got a bunch of alienated radical youth, most likely shooting their mouths off and making mistakes, who are going to be easy meat for the security boys.
