Perfect Plan

Well, I'd say that Al Qaeda was not only successful, but efficient:

'We think the Spanish government will not stand more than two blows, or three at the most, before it will be forced to withdraw because of the public pressure on it,' [an] al Qaeda document says.
'If its forces remain after these blows, the victory of the Socialist Party will be almost guaranteed -- and the withdrawal of Spanish forces will be on its campaign manifesto.'

Who's next? Poland? Britain?
