Cold War-- Take Two

I think the origins of the Cold War began sooner than i originally believed. After thinking about it more, I believe that the Cold War originated with tensions that began at the end of World War I. World War I ended quite hostilely, sparking Germany to react violently. Tensions between the US and the Soviet Union started when the two allies had disagreements on how to handle Germany. Tensions heightened when the USSR knew for sure that the US was a threat, proved by the dropping of the atomic bombs on Japan. Once the Cold War neared, economics became more of a factor in driving the Cold War. I still believe all the previously mentioned economic factors were a major cause of the Cold War.
