In 1977, the CIA and its daughter agency BND devised a plan in Munich to split Yugoslavia, a plan that was set in motion 14 years later and is coming along quite nicely today.
The 1977 plan envisions the then ‘Yugoslavia’ being split in multiple spheres of ownership, essentially turning them into colonies as the CIA put it eloquently on their map, with Slovenia and Croatia falling under German control (as they are today) and Macedonia turning into a US colony – as is the case today.
Serbia (without Vojvodina) appears to be left alone thanks to its “Russian ties”, however judging by who is leading the country, that’ll likely soon change.
You’ve got to hand it to the CIA, they’re quite diligent and follow through on their plans.
