If the antichrist is a single person, I don't think he or she will be from an existing government or monarchy – and especially not one as hated as these "Windsor" pudwhackers. It has to be someone who can charm cross-culturally and internationally, and who looks nothing but trustworthy, intelligent and capable of running a planet.

This, unless of course the global cabal can't pull that off and just rely on mass genocide and brute force, in which case any ol' sadistic wanker can be a figurehead.
