I think that if the general public were aware of the number of attacks in London that have been foiled by security forces there since the Gulf War 2 began, everyone there would move out to the country, and live as far away from each other as possible. This one apparently slipped through the net, and considering the potential of a well organised attack on London's public transport system during a peak useage period, Londoners were extremely lucky that the death toll wasn't much higher.
I guess all those years dealing with IRA bombers has prepared the British security forces well for this style of warfare, and with possibly the best police force in the world they may well catch the perpetrators. The problem of course is that there are so many cashed up extremist groups operating independantly of each other out there, that disabling this particular group will have little effect on the overall situation. The "War on Terror" can never be won using conventional tactics against an unconventional enemy.
Unfortunately the only way to assure that this doesn't happen again is to walk away from the situation in Iraq like Spain, Korea, Italy, Holland and the Phillipines have. I'm sure that Britain won't consider this option though, so it's inevitable that there will be further attacks in Britain until the situation in the Middle East is resolved. This certainly won't happen overnight, and we're now in a situation where if we walk away the whole region will collapse into a bloody civil war, but if we stay the incidence of these types of attacks can only escalate.
The extremists know that while we're all comfortable enough with our soldiers fighting a war on foreign soil thousands of miles from home, we won't necessarily have that same resolve when our families and friends are all real targets. Comparing this situation to the Blitz is sentimental rubbish, in that war Londoners didn't have a choice, they were fighting for their own survival. In this situation Britons know that all it will take for the extremists to go away and return London to their previous level of safety, is for Mr Blair to bring his troops home. Good luck guys, keep your heads down. Cheers, Terry.
