After the conclusion of World War II, when all interests had already been realised, and the former allies were no longer connected with each other, the difference in values and political practices came to the fore again. That is why Churchill's Fulton, Missouri speech on the Iron Curtain (which he delivered, incidentally, in the presence of Truman), turned out to be very useful. At this new historical moment, it was in line with the new geopolitical interests of the Americans themselves.
As a special reaction to this speech, it should be noted that there was a sharp change in the atmosphere among the defendants at the Nuremberg trials. It was clearly visible in the memoirs of both Germans released from prison and American psychologists who worked with them. According to this information, Goering in Nuremberg did not hide his joy at the fact that relations between the USSR and the Western allies had begun to deteriorate rapidly. He even predicted the imminent termination of the process and his own liberation, because, he said, America needs us to fight against the USSR. This last hope of Goering became a kind of flashback to the aforementioned last hope of Hitler in April 1945. Fortunately, it did not come true, and the Nuremberg trials were brought to an end. Regardless, this fact is very significant.
Is the same thing happening now in world politics? On the one hand, after Putin's Munich speech, and after Crimea, and now, in the light of recent events, many have begun to talk about a new Cold War, about a kind of ‘2.0’ version, using the analogy to computer software.
On the other hand, a fairly large circle of experts believe that this comparison is methodologically incorrect. According to this logic, the historical situation is different now, that there is no real (nor postulated) ideological confrontation, etc. Today's events are better described not in terms of the Cold War, but on the basis of other methodological grounds. Let's say, within the framework of the concept of revisionist powers, when it is possible to partially trace the shift from revisionism of interests to revisionism of values.
However, this sticking point of methodology is not particularly important in terms of general public opinion. What is important are the already clearly perceived and media-transmitted attitudes that consolidate the new gap and the new Iron Curtain. In this context, Biden's pre-election idea of creating a "league of democracies" as a new global institution fits well, which, according to all logic, will fight the opposite "league of dictators". A new global split in the world will acquire institutional outlines quite similar to the institutional logic of the Cold War. In any case, Churchill's old phrase about the Iron Curtain in today's politics does not surprise anyone and is by no means outdated.
