I have done some of the readings for the first unit about the origins of the Cold War. I thought I would put some of the thoughts down here to clarify my thinking before I participate in the discussions.
Legacy
With regards to the legacy of the WW2, the most obvious and probably the most important legacy is the division of Europe into two 'spheres of influence'. It is this de facto division of Europe at the end of the war in Europe that underlies the subsequent issues that led the great powers from a Grand Alliance in 1945 to an armed confrontation by 1948.
Chief amongst the issues are the division of Germany and the occupation of Poland. Indeed, these two issues seemed to be the most salient in the series of events that led to the escalation of distrust which in turn resulted in the breakdown of cooperation.
Of these, the occupation of Poland by the Red Army - a consequence of its 'liberation' from German occupation - probably is more significant. It is Soviet behaviour with regards to the Polish question that first planted the seeds of doubt and distrust in the minds of the western allies.
Also, the domination of Poland by the Soviet Union, and the latter's imposition and control of the political process within Poland set the subsequent pattern for Soviet behaviour in Eastern Europe. This in turn led to greater doubts and hostility on the part of the western allies.
This kind of behaviour, in turn, could be attributed to another legacy of WW2, the invasion of the Soviet Union by Germany that had led to so many Soviet deaths (anywhere from 25 million to 40 million), and immense damage to its industries and agriculture.
Understandably, such a horrific experience would only reinforce the Soviet Union's sense of vulnerability, which its immense but unaffordable armed strength, could not help alleviate, especially not with an American monopoly in atomic weapons.
Also understandably, the Soviet Union could hardly be expected to depend on the good will of other nations for its security, especially when we have to consider both Stalin's clinical paranoia (since the Soviet Union was totalitarian, the character of its supreme leader would play a very important role indeed) and the Soviet conception of the world through the lenses of Communism.
The western allies' unwillingness to be more accomodating of the Soviet Union, in turn, could be seen as a legacy of WW2. Or rather, of the origins of WW2. Their experience with Hitler in the 1930's was a powerful cautionary tale when it comes to accomodation of potential enemies. Accomodation then had still led to war, and it had been argued that if Hitler had been confronted earlier, the war in Europe might never have expanded and consumed so much in its terrible flames.
When confronted with Stalin, a dictator every bit as cruel as Hitler, and seemingly every bit as willing to dominate its neighbours, could the western allies have reasonably been expected to accomodate this other great dictator of the 20th Century? Surely at the back of their minds, they would ask themselves, if they do not draw a line in the sand and confront the Soviet Union, whether they would have to fight an even more catastrophic war in the future.
The Question of Inevitability
Reading the readings, I get the sense that the Cold War grew out of an absurd series of misunderstandings and poor judgements, that led each side to make moves that the other side interpreted as hostile or threatening, which in turn leads to a reaction that the other side would view as equally hostile or threatening.
The question surely must be raised as to whether the Cold War was inevitable. Or, put in another way, whether this armed confrontation that lasted for 41 years in Europe (I'm counting from 1948 to 1989), together with the huge expenditure in money, could have been avoided if one side, or both sides, had been more astute and more accomodating.
My initial assessment is this: it is difficult to see how much more accomodating the western allies could be. After all, they had virtually accepted Soviet domination of Eastern Europe, together with all that this implied in terms of oppression. Not even the invasion of Hungary and its bloody aftermath could provoke the West into making a stand. Aside from a few silly forays in infiltrating agents into the other side of the Iron Curtain, the West had left the Soviet Union pretty much alone in its running of Eastern Europe.
The West's acceptance of the de facto division of Germany and the Soviet sphere of domination (it's not mere influence!) aside, any other compromise on other questions might well have endangered or damaged the interests of the West. For example, it is hardly reasonable to expect the West to accept any solution that might lead to a united Germany under the influence of the Soviet Union. At the same time, it is also hardly reasonable to expect that the West would not take any measures to stablise the internal politics and economics of their own zones of occupation, considering both the potential humanitarian and political consequences.
This is another way of saying that it was unreasonable of the Soviet Union to expect the West to behave otherwise in their policies towards their portion of Germany. This is especially so considering the Soviet Union's unwillingness to participate in mechanisms to deal with such issues collectively. The Soviet Union might well have its own reasons, but this does not change the fact that its failure to participate in solving the problems collectively make it unreasonable to argue that the West should have accomodated it further, as this would effectively mean accepting Soviet interests, polices and even caprice, without question.
The question of inevitably, then, in my mind, rests more with Soviet actions than actions of the West. In this, I would say that if the Soviet Union had shown greater willingness to participate in collective mechanisms, and work with the west to solve problems collectively, the Cold War would not have resulted.
I also suspect that the Soviet Union would probably be able to participate in such collective mechanisms without endangering its own sphere of influence in Europe, as the West had shown no inclination to either subvert or wrest control of Eastern Europe from Soviet domination. In other words, the Soviet Union would have been able to achieve its security aims without at the same time alienating the West, leading to an armed confrontation that lasted 41 years.
All the above points are, of course, rough sketches or thumbnails of my thoughts. I would have to re-read some of the material to flesh out my points and thinking.
