You're right. China will not use forces to take back Taiwan; but on the other hand, Taiwan will not risk to declare independence. Many people from Taiwan open factories and run businesses in mainland China. Taiwan exports tons of things to mainland China and makes huge profit on it. Millions of people visit Taiwan as tourists. It would insane to stir up trouble from either side.<quoted text>I agree with your opinion.
It would be wrong if China had any motive of taking Taiwan back by force. Like I said before, it would be a shock for a peaceful nation to mirror the United States in its act (militarily-speaking, of course). I think that China's military build-up is not only for added defense, but also to flex its muscles in hopes of getting Taiwan to understand that while China grows stronger and develops more future weapons, Taiwan will eventually be in a position where it would possibly last a week or less if China dared to commit coercion.
However, I don't see China's military built-up as a threat. So far, China has not invaded any countries, while US has over 700 military bases. Do you call someone who works out everyday a potential bully? No, I don't think so.
