A big problem these guys now have is that they blew up a bunch of British muslims. Condemnation has been universal, even the crazies of the Muslim Association of Britain, who have all kinds of dodgy ties to militants in the middle east have issued a really strong condemnation, they called the bombings "heinous and repulsive" and urged Muslims to help the emergency services and police.
Right now, that is an opportunity. We obviously have an active service unit on the loose and if they didn't flee the country after this initial operation, they'll keep doing this kind of stuff until stopped.
As a Brit who spends a lot of his working life on public transport, and was very happy to give up wondering if I was going to die every time I stepped on it after the IRA went out of business, I want to see these guys looking up the gun-barrels of the SAS as soon as possible. We need British muslims 100% onside, so the perpetrators have no safe zone to hide in and so far the signs are surprisingly positive that this will happen.
Every idiot who firebombs a mosque, and a few have, makes the termination of this active service unit less likely.
I hope it will. However, I'm skeptical -- the so-called Muslim moderates are, IMO, intimidated by the nutter Muslims everywhere, including the US and Spain.
