A General Overview
The Cold War was an ideological war between the two world superpowers, the United States and the Soviet Union, beginning after World War Two.

An "Iron Curtain" separated Europe.

The state controls and plans all economic activity so that everybody benefits. Thus, it can be seen how different these ideologies were and how conflict could arise from these differences.
