I think this is a good a time as any to state that the stupid ‘flypaper’ excuse doesn’t work
Madrid may have been a lucky break. London (predicted several months ago) seems to indicate that it was not luck, but the result of an undamaged fundamentalist terrorist organization.
I will point out that neither London or Madrid is in Iraq. Neither is Osama bin Laden, who has now gone into the bloodthirsty fundamentalist franchising business. About all that's in Iraq are some spiffy jihadi training schools, where the package bombers of tomorrow get practical experience blowing up tanks, soldiers, and most importantly, civilians. Flypaper? I don't think you can call it flypaper when the little flies can buzz in, have afternoon tea, then take off and fly away to do their business elsewhere.
If you want to have nightmares, ask yourself "what stupid military policy will be implemented to distract attention from this attack?" The conservatives in Spain tried a stupid political distraction (shrieking "it's the Basques! it's the Basques!" when it was painfully obvious that an Al Qaeda franchise had blown up the commuter trains) which, thankfully for Spain, only resulted in the Popular Party being chucked out of office; Tony Blair might be evil, but he's not that stupid, so this probably means that some innocent bystander in the Near East will be the next to be converted into an Al Qaeda training ground. (There aren't that many secular Islamic states left in the Near East, so I expect that Syria will be the next to get it. And then we'll have three states where torture and pillage will be helping generate jihadis faster than they can blow themselves up.)
