This "war" was a very unique war, one of the reasons that is most known is that is a war were the people didn't have a physical contact, they don't FIGHT.
-The US doesn't liked the type of government that the USSR had so they fight with them.
(democracy vs communist)
It was a war of ideology, way of thinking they couldn't attack because they know that if one of them attack they will destroy all the country, it also was a arms race, it was a competition in all aspects, who went first to the space, a competition of technology.
Since 1815 to 1945 a multi-polar system was all around the world we can say that there wasn't a BIG ECONOMY that "controls" the world economy. but in 1945 the United States and the USSR the soviet union. but the united states won this war because the Soviet Union couldn't held so much waste of money so they lost that war, because it was so long, (1945 all the way to 1989/1991) since that year we have a unipolar system.
