I agree that naval power is required. Who supplies it and how it is applied are the things I think can change while still maintaining security. I wasn't thinking security would be provided outside of naval power.
You say "things can change while still maintaining security," but you have no plan for this. Don't you see why people are skeptical of this? And I don't blame you for not having a plan. I can't come up with one - certainly not one I'd trust. Would you want the naval power created by a multilateral institution like the UN (sorta like the idea of the EU army but on a bigger scale)? On the surface, that would be the fairest scenario since everybody would at least theoretically shoulder the load, but I sure as hell wouldn't trust any multilateral institution with that kind of power.
