The use of the term in the article quoted in the opening post, and so the question How many countries attempted cultural genocide?, is more specific than that.

Did something similar happen in Australia ? (e.g.link)

But how much of it was a consequence of colonialists making gains by enforcing economic changes that destroyed societies, rather than wanting to change cultures to be more like them ? That might include some areas of influence of both the USA and Soviet regimes (and maybe the World Bank).
