Just make sure that start-up is not backed by any cabal/pedo/deep state investors, and that you don't get blackmailed into something that'll you'll regret later. Good luck.
Strategically, you have to remove the keystone, or said another way cut the head off the snake. And to use another metaphor, the fish rots from the head. Smoke out the corrupt SES members. Find them, and the shadow government will fall. The lower level corrupts will no longer have their champions moving them up the ranks.
double meanings have been prevalent in Q Posts. RT = Rex Tillerson and also Real Time. Keystone is as you say, but it may also mean more symbolically than just that. And, certainly, the logo of SES is the symbolic keystone.
Is it important to distinguish between deep state and shadow government? The shadow government held in place by unelected lifer executives has circumvented the will of the people and allowed the deep state to remain in power. Or, maybe it's vice versa. SES seems to be more about the shadow government that makes sure the deep state gets what it wants. Or, have I got it all wrong?
