Saturday's vote in Ireland was the second time in 18 months that its increasingly disillusioned citizenry had to decide the fate of the European Union by endorsing or rejecting the crucial Treaty of Nice. The treaty seeks to revamp the union's administration and the hitherto sacred balance between small and big states prior to the accession of 10 central and east European countries. Enlargement has been the centerpiece of European thinking ever since the meltdown of the eastern bloc.Shifting geopolitical and geo-strategic realities in the wake of the September 11 atrocities have rendered this project all the more urgent. NATO - an erstwhile anti-Soviet military alliance is search of purpose - is gradually acquiring more political hues. Its remit has swelled to take in peacekeeping, regime change, and nation-building. Led by the USA, it has expanded aggressively into central and northern Europe. It has institutionalized its relationships with the countries of the Balkan through the "Partnership for Peace" and with Russia through a recently established joint council. The Czech Republic, Poland, and Hungary - the eternal EU candidates - have full scale members of NATO for 3 years now.
