It's such an insane series of events. It's just cope for anyone who think those videos are faked at this stage. It's gone on for too long without a clear debunk, and this confirms they actively tried to cover up their fuck up.
We know it was likely a US patriot who did time for leaking the videos, and the corroborating evidence for authenticity is just far too strong.
The US government agencies are harbouring some series fucking tech which make fake nukes look like childs play.
