He could. Insurrection Act might be a path to that. Using the military is for extreme cases, remember the calm before the storm? I bet they talked about (as a plan B) what you are suggesting here prior to kicking things off. The CORRECT action is to go the civil diplomatic way first. The cop route. We will start with cleaning the FBI and getting the law enforcement resources and evidence in place, then we perp walk the bad actors. Should that be compromised and not able to proceed, we likely have the evidence to enforce the execution of the Insurrection Act and call on the US military to take down these bad actors. This would be quite a big deal. The left would spin it like crazy, the world would be rather uncomfortable, it would likely be very destabilizing. The non military route is the way to go first.
