Samgheb, I think your purpose would be served just as well if you could produce authors who were calling for one of the other of these visions as opposed to a third party who says, “See, here are these two irreconcilable visions,” in the way Bagus does.
It shouldn’t be too hard to come up with a bibliography like that because such proposals had been floating around for literally centuries. I recently read Jean-Jacques Rousseau’s proposal for “Perpetual Peace through a Federation of Europe,” for example, which conforms more to the classical liberal model Bagus discusses. Mises himself called for an ultra-liberal regional or global state in “Liberalism,” if I recall correctly. Proposals for a more interventionist union shouldn’t be hard to come up with, I think.
