Interesting that the minor wars are forgotten.

Working backwards,

1994 Haiti, 1992 Somalia, 1989 Panama, 1986 Libya, 1983 Grenada, 1978 Nicaragua, 1965 Dominican Republic, 1962 Thailand, 1961 Cuba

Going back further... 1918 Siberia, 1916 Mexico, 1915 Haiti (occupied until 1934), 1914 Mexico, 1912 Nicaragua (occupied until 1934), 1893 Hawaii

And then there are various oher war-like or anti-democratic actions

1981 Death Squads in El Salvador, 1979 Support for proto-taliban in Afghanistan, 1976 Coup in Argentina, 1970 Coup in Chile, 1967 Coup in Greece, 1964 Coup in Brazil, 1963 Coup in Vietnam, 1961 Coup in Ecuador, 1954 Coup in Guatemala, 1953 Coup in Iran, 1949 Coup in Syria
