This is a huge propaganda win for the US and its allies. Whether it will translate into a win on the ground is yet to be seen. All indications are, and both Rumsfeld and Casey acknowledge this, while this may be a very important accomplishment, Zarqawi is not the reason for the insurgency and just because he is dead violence will not subside as a result. Nonetheless, the Americans badly needed a headline-grabbing tactical victory like this, and they have it now. Small wonder there is so much spin on this - I'm getting dizzy watching it all :)
