How is the iron curtain the dividing line?

Answer:
The iron curtain divides the line between the Western and Eastern part of Europe. In the Eastern part of Europe under the rule of the Soviet Union, Communism was the type of government practiced. While The other part enjoyed a democratic form of government. Neither country on either side was supposed "to go join the other side". Thus the iron curtain divided Europe but not for long.
