They're not really going far enough. You really need a full army, navy, air-force that is wholly accountable to the state government and is not connected to the US military.

You can guess why the feds don't want that.

In fact I'd go a step further and say the militias should all be local.

My only issue is that as local as they may be, they really do have to fall under some larger command structures for organization purposes. Most conflicts and emergencies are going to be cross-county. So you either need to start merging counties, or have a pre-built framework which the militias can fall into.

But there's also a huge extra issue. I'm not talking about only ground troops. I'm talking about both blue & brown water naval militias, and air militias as well. I don't just mean that as some libertarian fantasy, either. Decentralized, and discontiguous, low-kinetic warfare with the use of air & naval light vehicles & drones are going to be a more common thing going forward, and the only effective way to combat that is with similarly armed and organized militias. What that means is that your county's helicopter / drone squadron needs to be aware of, and in good communication with, your neighboring county's anti-aircraft militia units. Which means, even if the state is the sole commanding force of the militia, some sort of state apparatus will be needed for logistical, transport, and communication purposes.
