To suggest that the West could simply embargo China is crazy. If you can't embargo an Arab nation you are not going to be able to do it in China. Can you suggest a way the West won't die when the world's second biggest economy disappears? You know how much investment of the west is in China? And vice versa?
This is like suggesting to cut out the heart to save a finger.
Germany is not a good example, because Germany is not the Super power, at most it's a great power under the influence of America.
China is trying to take America head on.
The Chinese threat is just the most recent imaginary enemy for the US because of our differences and misunderstandings. We don't really understand each other. For every "human right abuse" of China aired in America, China has matched with an abuse by the US on their networks.
Interesting fact, while America broadcasting it's "defense" of Taiwan, China was saying how it was criminally "provoked" by the Americans. Same issue, two different sides. Nobody is wrong, but depends on who you want to side with.
Until the time when a third maybe alien force appears, earth will never lack conflict. two person one apple will always happen, it's just the people will always change in the scenario.
Lastly, on an English board, it would be really weird if everyone supported China because if that were the case, this wouldn't even be a topic of discussion..
