Unsafe at many speeds?

IT WAS, proclaimed every European head of government on December 13th, a moving and historic moment: the reunification of Europe, the real end of the second world war. Such was the hyperbole surrounding the EU's long-expected decision to open talks with five aspiring members from Central and Eastern Europe—Poland, Hungary, the Czech Republic, Slovenia and Estonia—plus Cyprus. In fact, the summit may have done as much to divide Europe as to unite it. It drew the first lines between the 11 countries likely to join the single currency in 1999 and the four, led by Britain, that will not. And it created a one-country ghetto for Turkey, which has been trying to move into Europe for over 34 years.
