Local armed conflicts of the Cold War.

We are talking about the period from 1946 to 1991, the conflicts were as follows:
Greek Civil War in the late 1940s. The last armed conflict in Europe was before 1991, followed by the Yugoslav war.
Korean War 1950-1953.
Two Indochina wars, 1945-1954 (with the French) and in the 1960s-1975 (with the Americans mostly).
Conflict between China and Vietnam in 1979 and the entry of the Vietnamese army in Cambodia and 10 years of war there with the Khmer Rouge (1979-1989).
Israel’s wars with the Arabs (1948, 1967).
Suez Crisis 1956 and Caribbean Crisis 1962.
The civil war in Nicaragua in the 1980s, the pro-Soviet Sandinistas against the Contras (they were supported by the US).
1979 War of Uganda and Tanzania.
War of Libya and Chad, 1978-1987.
War of Ethiopia and Somalia 1977-1978. It is interesting that they then changed the course of foreign policy: pro-American Ethiopia became pro-Soviet after the overthrow of the emperor, while Somalia, on the contrary, terminated diplomatic relations with the USSR.
