Where the costs of entry are minimal, there is a wide avenue of opportunity for those with little or nothing, which is why football is just about the most democratic sport of all: African and Brazilian footballers compete on a level playing field with their rich white European counterparts.
The starting point for understanding the deterioration in the relationship between the U.S. and Russia lies in Washington rather than Moscow. After 1989, Russia was a defeated power. Despite the fine words and some limited gestures, the Americans have treated it like one. Their policy has been one of encirclement.
Never underestimate the ability of political leaders to misread history on a monumental scale. The invasions of Iraq and Afghanistan have both served to hasten western decline: they have both failed to achieve their objectives and in the process demonstrated an underlying western impotence.
China has existed within very roughly its present borders for over two millennia and for virtually the whole of that period saw itself as a 'civilisation state.' It was only when it was too weak to resist the western powers in the early 20th century that it finally acquiesced in an arrangement that was alien to it.
There are a host of ethnic minorities in China, but they often have a weak sense of identity and are relatively small in total number. History has taught the Han that other groups will and should ultimately be absorbed and assimilated as Han. There is a belief that the Han enjoy a superior and far more advanced culture.
The era when the United States was the dominant global power is steadily coming to an end, and it must find a way of acknowledging this and framing its ambitions and interests accordingly. Instead of claiming the right to continuing primacy in east Asia, for example, it should seek to share that primacy with China.
Every major power always seeks to justify its action on moral grounds. Such behaviour is almost as old as the hills. The west has been a particularly vigorous exponent of this credo; and there is no reason to believe that China, for example, will be any different. But behind the moral rhetoric invariably lies interest and ideology.
