The publication of the new Wikileaks by The Telegraph draw my attention to some other articles in that newspaper. I specially like the comments by Ambrose Evans-Pritchard. This one is about how to deal with the rising power of China. If it keeps rising at one day it will take over from the US as the most powerful nation on earth.
The world has been in a similar situation before. Around 1900 Germany was the rising power and bound to take over from England. That had such a destabilizing effect that it ended with World War I. Just as we see now from China there was then a lot of German arrogance. But there was also a lot of paranoia among the other European nations that gave Germany the justified feeling that Europe was conspiring against them and envied them for their prosperity.
The article sees as favorable for the present situation that China has an aging population and that such countries usually aren't that aggressive. It may also help that the China's rulers seem wiser than Germany's rather foolish emperor.
But there are enough risk factors left and the stupidification of America's foreign politics with the rise of Sarah Palin and the Tea Party forms a risk too. I encourage you to read the article.
