Since the end of the Cold War, Germany has given two gifts to the world. The first was the decision to pour many billions of Deutschmarks into the somewhat patchy rebuilding of old East Germany. The second was to be the principal begetter of the euro – what was meant to be the final act to wind up the legacy of the Second World War. In a grand restatement of the principles that had cemented the original Treaty of Rome, Europeans who shared a currency would have so much in common that they could not dream of fighting each other. Some of the applicants to join the euro seemed a little odd or dodgy, but the Germans would ignore this because there was a higher, almost mystical issue at stake.
