The end of World War II in 2945 left a devastated and divided Germany. Immediately it was divided into four military zones among Britain, France, US, and USSR. The future of Germany was left in the hands of these four allied nations. However, before the end of the war, Germany was the common enemy, but now that it was over, there was nothing to support this alliance particularly between the US and the Soviet Union. Thus, each nation had their own self interests in mind and wanted to reunify and rebuild the fragile Germany according to their own ideologies and beliefs of society. As a result of the US and the USSR trying each to influence and model Germany after their own country, tensions developed which helped create the Cold War.
Tensions developed in Germany first when the military zones of Germany were not reunified due to the USSR not wanting to hold free elections and because the USSR wanted to keep Germany weak economically, politically, and socially so that another German world conquest would ever occur again. The US, however, wanted Germany to be economically and politically sound in order to stabilize the global economic cycle. This difference in what would become of Germany sparked the tensions that would increase in Germany and ultimately play an important role in the cause of the Cold War.
The escalation of tensions in Germany occurred when USSR implemented the Berlin Blockade which closed all access routes to East Berlin. The US responded by initiating the Berlin Airlift which sustained Berlin successfully for over a year by airlift thousands of tonnes of supplies, food, and coal. Eventually, Stalin called off the Blockade and it demonstrated the fortitude of the West and of the Berliners because they were able to successfully resist Soviet communist aggression.
After Stalin died and Khrushchev took charge of the USSR, he created the Berlin Ultimatum which told the US that if Berlin wasn’t reunified in 6 months then the Soviet Union would close off all access routes between East and West Berlin. The US refused the ultimatum which was insisted upon by Khrushchev twice. After refusing the second time, Khrushchev built the Berlin Wall to prevent the East Berliners from leaving East Berlin. This conflict made the Iron Curtain come to fruition and created a visible sign of the Cold War.
In conclusion, there’s no doubt that Germany played a major role in the tension of the Cold War. Nevertheless, there were other factors that led to the Cold War. These factors include the Korean War, the U-2 spy plane incident, and most importantly the nuclear arms race.
