My opinion, Not reading too much into it. This assembly does not include Space Force, as it had not been stood up at the time photograph was taken. Our take on Space Force was that it was a clean and fully vetted branch of the military. Which means 1 the other branches were not clean and 2 countermeasures were taken. Important points that should counter the military is compromised dooming to an extent. The problem was identified and countermeasures were taken.
