Well, remember, we're used to terrorists who do have reasoned motives and a coherent political agenda. We eventually persuaded the IRA to stop blowing us up with a combination of very precisely targetted police/spook work and a political compromise. It's far from clear how you'd do that with the presumable perpetrators of these bombs though.
But, IMO, anyone who blames this attack on Blair, or your noble involvement in freeing the Iraqi people and fighting this war on Terror, is willfully ignorant of history, and what terrorism is.
My prayers continue for the people of London, and all of England. You are great allies, and we are thankful!
