Don’t the WEF/NWO know that the depopulation could work the other way too?
Well, the ruling elite of the NWO and the WEF are so wealthy and powerful that they literally own governments and with that they control their respective militaries and all of the technology in use to include surveillance that monitors their isolated mansions. They are extremely well protected and geared up to survive no matter what the threat is. So realistically, no, they aren’t concerned about retaliation from the people in general.
