I would be much grateful if you could read my argument for the breakdown of relations in the 1940s and suggest ways for me to improve it.
The period between 1943-56 saw relations between the USSR and the USA worsen. It is argued that the primary reason for this is the change in American presidents in 1945. Following this change in presidency, relations continued to worsen even more with the Truman Doctrine and Berlin.
Truman’s attitude towards communism and Stalin was the initial and most significant cause for the change in relations from 1943-56. Prior to 1945 relations between the USSR and the USA had been smooth – both nations had made agreements at the Tehran and Yalta conferences. However, in 1945 American president Franklin D. Roosevelt died and was replaced by Harry S. Truman. Truman believed that Roosevelt’s approach to communism had been too relaxed and that a firmer hand was needed on dealing with it. This was exactly what Truman had. In August 1945 Stalin and Truman met at Potsdam. The conference, unlike the two previous to it, was a failure because Truman took an aggressive attitude towards Stalin – continuously disagreeing with his proposals and even telling him what to do. This enraged Stalin and caused a personality clash which worsened relations from then onwards. The fact that relations worsened at Potsdam is linked to the fact that only one proposal was agreed there.
In 1947 the Truman Doctrine only proved to worsen relations further causing arguably the lowest point in superpower relations between 1945 and 1956. The doctrine, which promised economic aid and military protection to European countries threatened by communism, totally undermined Stalin’s influence and power in Eastern Europe. The threat of American influence in the Soviet sphere – which Soviet leaders knew would sway communist countries to turn capitalist - angered Stalin further. The formation of Cominform, which forbid Eastern European countries from applying to receive Marshall Aid, is an example which shows how angered Stalin was.
Another reason why relations worsened was because of the agreements made between the Western nations about West Germany. In 1948 the USA, UK and later France agreed that Western Germany (which was split in to three zones, between the three nations) should be unified as one zone. It was furthermore agreed that the zone would be controlled by an assembly of officials and would have a currency, the Deutschmark. However, Truman made clear that he did not want Stalin involved and so Stalin was left out. For Stalin the thought of a new constitution in West Germany that would have no influence from him was highly concerning. He, therefore, decided to blockade Berlin, stopping all entry to and from the city via land - Berlin being in his zone of Germany - in the hope that by cutting the Western nations off from their hub, he would stop their plans. Publicly, the blockade was a disaster for Stalin because it presented him as a controlling dictator, but a triumph for Truman who calmly overcome the problem by airlifting supplies to the city - thus avoiding war. Between 1948 and 1949 Truman had, in effect, humiliated Stalin to the world. It is clear that this worsened relations further because just months later the USSR started to build up its military inflicting an arms race.
The era of 1943-56 saw relations worsen dramatically. Although relations were clearly worst off after the Truman Doctrine and Berlin incident, than immediately after Truman took office, it is argued that Truman's entry was the most significant point of the era. The main points which led to a breakdown in tensions were all inflicted by Truman and so it is not unreasonable to argue that if Truman had not replaced Roosevelt then relations would not have worsened as dramatically as they did.
