Every country is controlled by a group of people (Sabbatean frankist's proclaiming to be Jews as smokescreen cover; allegedly).

This is group knows no borders and is faceted throughout the world. Each country was given a script slightly tuned for each one to seem different.

This all part of the plan to control and genetically alter humanity into synthetic hybrids. They're running out of time and moving fast and it's not going as smoothly as they've hoped.
