Why do we call the conflict between the United States and the Soviet Union the Cold War? Why did it never become a real war?

It was never a real war it was a series of poltical and proxy wars that neither nation took underneath their banner for example Russiaa never invaded the United States The Soviet Union was trying to influence and support countries to turn communist and the Us was trying that but to make them capitalist for influence. It never became a real war because the Nations were both extremly powerful with their nuclear weapons and influenced countries and their armies were so poweful that they didn't actually fight because they thought it would be destrcutive to both sides and the rest of the world so thats why they tried to one up each other sorry for the poor grammar and spelling I had to write this quickly have  a great day :D
