This is most likely a strategic move by a foreign adversary. It puts the JCS in a difficult situation. If they claim the letter is fake, the leftist media mob will be all over them and the talking point will be, "Well is the military NOT on the side of Biden???"

It also forces the JCS to actually condemn the capitol "riot," or they will be thrown to the mob by the leftist media. The article itself may as well be very real given the gravity of the situation, and the fact that CNBC scooped it up shows that we are dealing with something much larger than an organized shill operation.
