The problems have been globalised and the nation-State has no way of reaching them. The problem of pollution, with the destruction of the ozone layer; the spread of terrorism; AIDS or other viral diseases; the internationalized financial system; nuclear potential; drug trafficking; extreme poverty. All problems that have forced the creation of supranational or transnational organizations where the word sovereignty has become hollow. The nation-State has already lost the monopoly of control events within its territory. This transfer of the old concept to supranational entities does not seem to cause positive results. This should add up to tribalism and regionalism. Boy Scouts of America might disagree with that approach.
The most advanced of the processes of construction of large spaces supranational, European, presents crisis of impotence in advance, although existing institutions function fairly acceptable way. The political shape of Europe stops at national polls, while every day more people from the countries that comprise it considered to be European, rather than Italian, German or Spanish. That is, disintegration in the practical scope and loss of the original sense of nationality for the sake of a greater where the old nation-State is considered just a member of a much wider community. Perhaps we can say that these statements only serve to maintain the internal order in the social and political. Economically they have been replaced by the transnational financial and multinational consortiums, as we see every time.
Perhaps the most visible example is the airlines, formerly national inner pride and which now remain only the name of the old membership. It is clear that the Organization of continents continues as belonging to nation-States, but weakens as it progresses in its Constitution. With a few exceptions no longer a State with own hierarchy in international power. The revival of the local is a phase of high interest in the process of lethargy and collapse of the nation-State.
