This. They are desperate.
They know that they cannot count on military intervention, now that the Mueller investigation is a dead duck and the SC is going to go Trump's way. This move is a crappy Hail Mary asking for volunteers for martyrdom.
It will have limited effect, save to provide an escape hatch to any medium-to-high level cabal members still in the government. No one who actually realizes what is going on would take them up on this offer.
