NATO and The Warsaw Pact

The NATO is the North Atlantic Treaty Organization.
The Warsaw Pact was formed by the soviet unions allies.
During the Cold War tensions were high and even though there was no actual fighting involved there was still a threat of war that the U.S. and the Soviets could not afford to ignore. It was that threat of war that prompted the U.S. to form an Alliance with several other countries who were also against Communism like France and Great Britain and named this Alliance NATO which stands for North Atlantic Treaty Organization. The Soviets, having heard of this Alliance felt threatened and formed there own alliance with countries that supported communism and they named there Alliance the WarSaw Pact. So basically the NATO and WARSAW PACT were precautionary Alliances that were made to feel more secure during the threat of Nuclear war in that time but of the two only NATO still runs today.
