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.
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
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.
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.
