The cold war its very own verbiage. the west had more than its share: cold war, iron curtain, containment, domino theory were just a few. what did they mean in this strange new post-war environment

The cold war was a period of non-confronting political wars. The term "Cold War" comes from the war not being fought in a battle field yet through politics and through allies. The iron curtain was a speech given saying that communism would put a curtain over Europe. The Domino Theory was part of the reason the United States became involved in the Vietnam war. It stated that if one region of an area failed to communism more would follow. Containment also involves Vietnam. We tried to contain communism from the north from the south.   

In my honest opinion , i’d say franklin d roosevelt was a president that impacted our nation , i say this because fdr is voted among top three best us presidents and he was the longest serving president by 3 terms , usually presidents only supposed to have two terms increments of 4 years , equivalent to 8 years total before election time. and he established the fdic , through the 1933 banking act and he established the us , social security system , during his presidency, and established a national minimum wage , through the fair labor standards act , fdr led the allied coalition to victory in wwii and he played a major role in the creation of the united nations.
