Thanks for asking! Argentina: 1890. Chile: 1891, plus direct support for the 1973 coup. Sorry about Paraguay and Brazil, US merely engineered and directly advised murderous corrupt dictatorships. Invasions however also include Bolivia, Costa Rica, Cuba, Grenada, Haiti, Mexico, Uruguay, and Venezuela.

Regarding South Vietnam, does "full cooperation" include assassination of their president in 1963?

The examples you cited for Argentina and Chile were -- in both cases -- the US sending a landing party of Marines to defend the embassy grounds during political unrest. That's an "invasion"? OK....
