Earlier quoted context omitted.
Just as a side thought... if you look long enough at any country's history, you'll surely find horrors and terrible individuals. But that rarely means that country or its modern descendants would want to be "liberated" by a foreign conquerer, whether that's China or the USA. Forced assimilation is a form of genocide and people would almost always choose to be oppressed by one of their own rather than a foreigner...
Doesn't every country have official languages that they teach and conduct business in? There are very few groups who still speak their native languages after being assimilated into the US. Tibetan is still being taught in schools there along with mandarin. Wouldn't it be hard to integrate into the business community if you didn't speak the official language of business in a given country?
Even in "monolingual" countries this is true to some extent. Most of the people likely to be in here right now are are in countries clustered along one side of the spectrum, that we are a minority and an outlier.
