Thanks to WikiLeaks I'm wondering on a certain question as of late.
In some cables of Cablegate, the US Embassy in the Vatican clearly sees the Holy See as a supranational institution that, in it's foreign policy, should be treated as a nation-state.
I was wondering how this relates to the status of the EU as a supranational institution, which in it's foreign policy should be treated as multiple and different nation-states.
Any ideas on this?
