The European Union formally welcomes 10 new members on Saturday, in the process extending its borders all the way to Russia's doorstep. It is a monumental triumph for the architects of European integration, and with agreement on a draft constitution for the EU now within reach, they could soon have even more reason to break out the champagne. Still, forward motion does not always denote progress.
The EU is being enlarged, but it remains an unaccountable and, in many ways, undemocratic institution. It's also an increasingly unpopular one. Amid wrenching social and economic changes, the rush toward a European super state may well be laying the groundwork for a nasty backlash.
