Because the US and the USSR were world powers. World powers are called world powers because they EFFECT the world.
The cold war was world wide; and commenced in 1945 and ended in 1990.
There was only one atomic age...which created the cold war; thus there was only one cold war; 1945-1990 & it was world wide.
The collapse of the Soviet Union and a softening of communist governments world-wide.
World War I, World War II, and the Cold War
Yes, the Cold War was after World War 2
The most terrifying aspect of the Cold War for most people was that it might turn into a hot war involving wide use of atomic weapons, thus destroying human civilization, if not all life on the planet.
It was alled the cold war because it wasn't an actual war. Compared to a "hot" war (a standard war with actual conflict/battles) this "war" was "cold" because there wasn't any fighting. It was a world wide rivalry between the Soviet Union and the United States, but there wasn't any actual fighting
The cold war was NOT declared. The cold war was not a war. The cold war was simply a name given to "a non-shooting" military stand off between the communist world and the free world.
World War 1 was not a cold war because of all the people that died the only time that there has been a cold war was after world war 2 and that was before the Korean war happened i hope this helps
Korea and Vietnam were the only HOT Battles of the cold war; a war between the communist world and the free world.
World War Two was an origin of the Cold War.
Do you mean, "Why was the era AFTER world war 2 called the cold war?" Because no one calls the era of WW2 the cold war.
