I don't think the dominance of English has much to do with the quality of English or American cartoons or their wider culture. Even ignoring the British Empire, the USA has been one of the largest ever continental empires for 200 years and is now a quasi hegemonic global empire with around 600 overseas military bases and the ability and willingness to launch military strikes and enforce it's will across large swathes of said empire. Knowing the language of your overlords has always been a good idea and English is now even more widespread as a second language than when the British were stomping around engaging in the odd genocide and searching for a decent meal. I suspect that even if Germany produced the most amazing cartoons in the world only a tiny fraction of people would ever to learn it compared to English. That's what dubbing and subtitles are for.

Having said that, between roughly 1850 and the end of the second World War it was considered necessary for engineers and scientists in the UK and USA at least to know German because of the German's achievements in science and technology (especially chemistry) and the political and economic power of the various central European states and empires controlled by German speaking elites. Gaining a competitive advantage over your peers and expanding your knowledge has always been a good incentive to learn another language independent of wanting to learn what your occupiers are saying.

In Eastern Europe the Soviet Union was that "hegemonial force", yet most people didn't care to learn much Russian, even though it was mandatory in school (for instance in Eastern Germany) and fluent Russian would have opened up some juicy carreer paths. My English was much better than my Russian, mainly because of the cultural influence via Western radio and TV. The Soviet Union simply wasn't "cool" for an East German teenager in any way.

I had excellent reading and listening comprehension by the age of 12, and could speak fairly fluently by 16. I don't think geopolitics had anything to do with that. The kids in my class that didn't watch foreign TV had significantly less skill in this regard.

German kids watched TV with dubs because their network execs deemed it worth it, I don't think that was very political either.

It's not the military.

Most people really learn English because of economics. American companies are big trade partners, customers and of course, employers.

Many of the others learn it for cultural reasons, as said. Cartoons, movies, TV series, songs, etc.

Japan, being an island nation, shows many strata of imported words in its vocabulary. Chinese was the original source as the language of the intelligentsia for centuries. When first the Portuguese and later the Dutch came along and were granted a trade monopoly, Japanese picked up words from both, and when the Meiji reformation opened up the countries, huge slabs of medical and technical German were imported. Now, of course, English is the predominant source of loanwords.

It has everything to do co Cartoons. It is all about cultural dominance. Many tv shows i watched in my youth were in English, as were many of the videogames I played. That is the only reason I learned English. I you put a kid in front of a TV with mostly English language but subtitled movies and series, he's speaking English in no time.
