Code Geass series also depicts America (through strong British culture ironically) very negatively.
Yeah I was following that in Adult Swim. It looked like an alternative universe, where these is no USA, no American Revolution, and instead a monarchy called Britannia was established, although Britannia itself is not in Great Britain. GB appeared to have been conquered with the rest of the European Union by the Empire of Britainnia. Behind the monarchy is probably the most right wing, elitist, pro-Darwinian form of government ever invented based on the concept might is right.
China in the series is portrayed as never having undergone its own revolution at all, so it remains under a dynasty controlled by eunuchs under the name the Chinese Federation that appeared to rule much of Asia including India. The Federation is supporting the Japanese revolutionaries against Britainnian rule, though their own motivations are also self serving.
Later on in the second season (R2), the Japanese Revolution becomes the United States of Japan, although its a government in exile until Area 11 (Japan) is taken back from Britannia. The Chinese Federation falls as the eunuchs were deposed, and the government is replaced by the United States of China, which allies with the USoJ. (Since its an anime, both Japan and China are represented by cute princesses). Then along with the remaining states that has not fallen under Britainnian rule, they form the United Federation of Nations.
