It will not save them.

Yes, they will murder billions. But sooner or later they will be eaten by those they wish to dominate.

We will dig them out of their bunkers one way or another.

They will have their private farms, private woodlands to roam while the normies slave at Starbucks and WinDixie. They will farm the pure bloods too. Humans especially those of us that are rarely medicated and unvaxxed will be expensive to obtain. They won't kill many of us; more likely will round people up. I plan to be in the wind.
