None, the cold war wasn't a war.
However...Korea & Vietnam can be considered two "battles" of the cold war; since Korea/VN were "hot" (shooting & killing) wars during the cold war.
The cold war was about communism vs free world. Korea/VN were both fought between communists and the free world.
so what were the major battles of the cold war and why
Hot "battle" of the cold war. A war is a series of battles.
Korea and Vietnam were the only HOT Battles of the cold war; a war between the communist world and the free world.
No battles . I think you are missing the point of the Cold War because there were no battles it was called "Cold". There were a few standoffs and threats, but for the most part it was the western powers looking at the communist dictatorship through the lens of containment.
The cold war was cold because there were no battles, therefore no one was killed in combat.
As one of two hot battles of the cold war.
The Korean War (1950-1953) & The Vietnam War (1961-1975) were "Hot" battles of the "Cold War."
Cold War means NO FIGHTING. There was no war during the cold war, with the exceptions of the two "HOT BATTLES" of the cold war, the Korean War and Vietnam War. Actual war between the the USSR & the US never happened.
Vietnam
Both were "hot" battles of the cold war.
The ten biggest battles of the US Civil war were The Battles of Bull Run, Antietam, Fredericksburg, Chancellorsville, Gettysburg, Vicksburg, Chattenooga, Cold Harbor, Petersburg. (There were two major battles at Bull Run.)
