While certain coastal cities have become very prosperous, the rest of China has a per capita income of $200 a year. The coast wants to have nothing to do with the interior; it wants to work with Tokyo and New York. This is an old story in China. It is why Mao succeeded in 1927.

He came back to Shanghai and sealed off the country.

The key to forecasting is to understand both the constraints nations are under and the manner in which the struggle for power shapes leaders.

The poets think about war more than the social scientists.
