Which was the more important cause of the development of the cold war.
• the berlin blockade 1948–1949
• the korean war 1950–1953?
you must refer to both causes when explaining your answer.

The Korean War was already a proxy war during the Cold war: the Cold war has already been ongoing then.

The Berlin Blockade was earlier, and it can be assumed to be the beginning of the war: the Soviet Union decided that they can't risk loosing control of their occupational zone in Berlin
