The current model of “democracy” in the US —and indeed in most countries— is very arm’s length.
In countries with a model closer to direct democracy, Switzerland being the best example I know of, it might be possible to hold a vote about a specific policy (e.g. we don’t want our army to develop/use autonomous AI hunter-killer drones) but micromanagement of multiple policy decisions is probably both difficult and maybe unwise. Defence topics might be especially challenging given the background knowledge required to make a rational decision may often be classified and/or otherwise unavailable to the general public.
