It would logically be a better plan to get control of either the Deep State or Biden and play through them, rather than start international or civil war by having Trump go into dictator mode.
The public doesn't know who the private controllers of the DS are to cry about their overthrow or infiltration. If the military has control of Biden, then they have plenty they can hold over Biden's head.
Q said that it would be swift and clean. The inevitable bloodshed that would occur from direct action before the inauguration would not be clean. Q said that we'll love how it ends. It's not over yet. If they had control over Biden it would be PERFECT.
An arrest would be a military coup.
Not if the election was rigged. Illegitimate POTUS.
That is a possibility. Is the missing “against all enemies, foreign and domestic” in the oath enough to call it illegitimate?
The military most likely has all the evidence they need.
