Well, unlike Germany, these little people don't have big enough heart to admit their wrongdoings in the past. That's why they never really dominate us, the other Asians, unlike how Germans dominate the other Europeans. They are not big enough to carry that burden, that weight to become an example to lead us through perilous, dirty, and cruel world. Their economic and industrial reign was rather short, like their WW2 achievements.
If one would recommend the leader of the world. I would say, the Chinese has the most experience, but sadly their current heading was rather shoddy and their vision is too blurred. Probably, the US is the best of the worst choice as of now. I would recommend the Brits too. But they are all suffering from one big problem as a leader of the diverse world.
Clearly, the west still suffer from that "double standard" issues. Take a look at Ukraine for example. This potential ally was in turmoil, and those Russians in Crimea and Eastern Ukraine don't want to be part of that deal, so they chose to secede. They simply won because their overwhelming numbers in the population. I have to admit that Russia is quite an asshole by moving in first. It is an illegal act, but the Crimean people's choice is theirs. You can say they were voting under gun totting ethnic Russian mobs and Russian Navy personnel, but if you look at the composition of population, you'll see that holding a fair referendum there isn't the best interest for Ukraine and the west be it without Russian intervention.
So what's the deal with Ukraine' territorial integrity. The Chinese was once stripped of Xinjiang, Tibet, and many other Central Asian countries, including Russian-Manchurian borders along its course of history. Clearly, the Han Chinese were minority there. But why they were supported to secede? Especially those who were part of China in 1949? Then the independence of East Timor, which Indonesians still try to reason on why these Portuguese-speaking fellas don't feel that 1945 spirit. We try to justify that being occupied by Portugal isn't like being occupied by the Dutch (like the rest of Indonesia), they just don't share that 1945 feeling, and them being close to communism, was just like us before 1966.
