Of course the ‘official’ Cold War still lay in the future. But in certain respects it had begun long before May 1945. So long as Germany remained the enemy it was easy to forget the deeper disputes and antagonisms separating the Soviet Union from its wartime allies. But they were there. Four years of wary cooperation in a life or death struggle with a common foe had done little to obliterate nearly thirty years of mutual suspicion. For the fact is that in Europe the Cold War began not after the Second World War but following the end of the First.
