Last November, celebrations to mark the 30th anniversary of the fall of the Berlin Wall were overshadowed by a palpable sense of unease in parts of Europe. To be sure, the events of those weeks through late 1989 and beyond were hugely significant - iconic moments in history that came to symbolise the end of the Cold War and the decades of nuclear-tipped standoff between West and East. Many Europeans felt that things could never be the same again, that their continent had seen the back of communist totalitarianism and repression and that a new age of peace and prosperity and democracy beckoned.
