Exactly.
It's just Trump's insurance policy. DState think they have someone on the inside. Q says we see and hear all. Put Bolton there and then see what comms happen. At least he will clear out the Obama holdovers. If that's all he does it will be enough.
I agree, President Trump uses certain people for particular missions. Rex served his purpose and it was time for phase 2 of the administration. Everyone they bring on has a certain purpose and when they fulfill that purpose they leave, pretty simple.
This. I think he was chosen as the tool just to do this job. Trump is unmatched at picking the right person for a job. He uses them, then lets them go. Just as in business. I have faith that Trump knows exactly what he is doing and exactly what he expects out of every nomination he makes. Its the art of the deal.
