"WITHOUT THE AMERICANS YOU WOULD BE SPEAKING JAPANESE AND THE EUROPEANS WOULD BE SPEAKING GERMAN TODAY!"
Every time I hear crap like the above, I feel like throwing up. And I seem to be hearing more of it these days. Has Uncle Sam been churning up the propaganda now that the US economy is going downhill?
First of all, what's wrong with speaking German or Japanese? I actually did a one-year German language course back in university. When you speak only English, all your information is effectively censored by the English-speaking British and Americans. For instance, when I look for books on Germany, all I find are travel guides and biographies about Adolf Hitler. Germany is/was the biggest exporter in the world and nobody writes about it!
Second of all, China was actually conquered and occupied by Manchuria from 1644 to 1912 (the Qing Dynasty). Today you won't find Manchuria on a map! Manchuria was absorbed into China and is now Heilongjiang, Jilin and Liaoning in northeastern China! Are the Chinese speaking Manchurian today? Nope, they are speaking Putonghua (or Mandarin)! The same would have happened to the Japanese if they had stayed in China long enough!
Third of all, the USSR - not the USA - defeated Nazi Germany. Look at the Soviet Union's sacrifice compared to America's. What the Yanks really did was to block the Russians from occupying Western Europe. So, without the US, Europe would been speaking Russian, not German!
Look at the USA's teeny-weeny contribution during WW2. The Americans like to over-rate their performance and take all the credit - with lots of help from Hollywood. And the historically-challenged folk swallow it without question. That's what happens when the English-speakers control the mass-media!
