I believe the country was created to be a voluntary union of the several sovereign states.

If it is a voluntary union of the several sovereign states then why is permission needed for a new state to join? That sounds like an organization that controls who it lets in.

I must be missing something. The military is currently an all-volunteer force — but they don’t have to take everyone who applies. They control who they let in. But it is still a voluntary force.
