Time alone will tell, of course, but I see no reason they wouldn't want to accelerate the killing, even to a pace that strikes the average person as far too quick.
Gates publicly stated 15% population reduction. Do you think the comments would have slipped past as many people if he had said 90% population reduction? The Georgia Guidestones clearly mention reducing population to 500 million. That is where the Gates' of the world want things to go and it is not like they have centuries remaining themselves. The past year-plus makes it crystal clear TPTB are getting anxious and are willing to take enormous risks to get what they want, which is NOT complete control over BILLIONS, but MILLIONS.
They have so much food, ammo, etc., stockpiled in remote locations, why not just kill off the rabble en masse?
I do not claim to know exactly how they will proceed. Any such predictions would be a fool's errand. However, absolutely nothing would surprise me at this point. They want that VAST majority of the human race DEAD -- now, not 100 years from now.
