Not trying to sound like a jerk, but the federalist papers clearly say that the militia is comprised of the whole of the people.

The "militia" is the whole of the people, but states have put up their own state militias. Theoretically those militia can be better stocked and organized for emergencies such as tornadoes, hurricanes, forest fires, etc. Unfortunately, in most cases these state militia are not well-funded or organized and are basically just a joke.

Maybe it would be best to have neither state militias or a National Guard. But if we are going to have one or another and people really care about the tenth amendment, then it would only make sense to have state militias rather than a National Guard.
