Can someone explain me cold war in details, i know what it is but i need an explanation in detail

The Cold War was more tension and distrust than a war. The Cold War was between the USA and the USSR. There were never any large scaled battles, but both sides had plenty of weapons in case a large scale battle was imminent. The Cold War was mostly proxy wars, psychological warfare, propaganda, and espionage. While both sides never had any large scaled battles, or even really went to war with one another, they were both armed with Nuclear explosives. The war pretty much ended after the Neutral Bloc, seeking good relations with each side, called the Non-Aligned Movement. Hope this helped!
