<em>Checks and balances </em>are a tool used in a political system to decrease the risk of centralization of power. They ensure that no one person or department has an absolute control over decisions. Checks and balances create separation of powers. In the U. S. checks and balances are exercised through its three branches of government: the legislative, the executive and the judicial. Each branch has special abilities. The legislative branch makes the laws but the executive branch gives the veto power to the president to veto these laws if necessary. The judicial branch may deem certain laws unconstitutional thus making them void.

The Iron Curtain represented the constant conflict and physical division between the Democrats and the Communists. This term was used to describe the conflict that existed from the end of World War II (1945) until the end of the Cold War in 1991. It is important to understand that the Iron Curtain was a concept used to describe the ideological division of Europe and did not physically exist. Although the Berlin wall was a very significant representation of the Iron Curtain, no one border or wall was the Iron Curtain.
