Just after the Communist victory in Vietnam, the People's Republic China invaded its southern border with North Vietnam.

The Soviet Union and the PRC repeatedly duked it out over Mongolia.

While not an actual member state, Yugoslavia had a mutual defense pact with NATO so as to keep a lid on Stalin's long-unfulfilled dream of a warm water fault.

The Russian Federation's invasion of Crimea is because warm water port.

Yugoslavians could travel freely to Italy. To assert its neutrality, Tito permitted precisely two port of call visits each from United States and Soviet Naval vessels.

My father was the antiaircraft missile fire control officer on the USS Springfield on one such call. Mom got to fly over to hang with Dad behind the Iron Curtain but strangely me and Jeannie weren't invited along.
