“Blair must have been in on it, ….”
We can only speculate, but I doubt Blair was in on it. Too low level. In my estimation politicians are just the hired help. Long before they reach high office they are picked out as promising material, taken aside, perhaps after being invited to a Bilderberg meeting, and offered rapid advancement and rich rewards if they promise to follow orders when the time comes. At most Blair was probably warned something big was going to happen and to be ready to take instructions when it kicks off.
Blair proved a loyal servant to the puppet masters and so now he is allowed to swan around the world doing odd jobs for the elite, visibly demonstrating the rewards of compliance, a counterpoint to the likes of Gaddafi, who died on camera with a bayonet up his arse to teach other national leaders the rewards of defiance.
