The paper distinguesh political and strategic phases within supranational unification processes. In the first the need for some form of unification arise and is publicly discusses. In the second it is possible to obtain specific steps in that direction when certain comcomitant conditions arise. The paper suggests that the globalization debate shows that the political phase of world unification has started. At the same time it suggests that the strategic phase has not started and that those concomitant conditions are unlikely in the current international situation.
