That’s what I heard. Because they needed to kill us in stages, so they could blame each stage on anything but the real weapon. Each rollout gets another 20%. If they tried to do it all at once, then the jig is up. Everyone would KNOW they are being murdered by the weapon.
Their plausible deniability would be out the door in an instant.
So rollout in stages was decided upon. And that is what we have seen in the first six months.
