I remember reading a pamphlet from the PCF from back in the 50s arguing about how american imperialism won't just be an economic stranglehold on Europe but also a cultural one through the promotion of cosmopolitanism as a vector supplant the respective national cultures of Europe with the American culture, akin to how invasive plant species can overrun local flora.

I think Rammstein's song 'Amerika' pretty much summarizes the whole concept in a catchy song
