This is a very skewed reading of actual history.

The USA's efforts in South America (for example) were not aimed at spreading liberal democracy - the USA routinely intervened after democratic elections appointed leaders they didn't like, and installed military juntas or dictators that they did like. There was an overt tendency in US foreign policy to install right-wing leaders where possible, partly as a defence against Cold War Communism.

The wars that the USA engaged in since WW2 have not been about promoting liberalism, or removing totalitarian regimes. They have been explicitly about protecting US economic interests abroad, and generally feeding the military-industrial base as Eisenhower predicted.
