EU is a great experiment on supra-nationality, where citizens of countries agree to form a supranational body which will govern them on certain specified issues rather than their own political masters.

Should EU succeeds, it may set an example for other countries, like the Asian countries, South American and African Countries to follow suit by forming their own supranational bodies.

Eventually, all these supranational bodies then can coalesce and form a global supranational body with a Global Parliament and Global Commission, where the Global Commissioners will be required to take an oath of supranational loyalty in which they swear to act completely independent of their nation state and neither seek nor take instructions from any government, in order to act in a way that best promotes nothing but the Global interest.

Well this may sound quixotic but 70 years ago any suggestion of the present EU would have sounded quixotic too!
