The answers to both questions is no. Trying to isolate China will only make the lives of Chinese people worse and extinguish any hope of democracy in the medium term. But the US is terribly afraid of losing its grip on power, so it has to be.

Second, the country that is now invading the privacy everywhere in the world (anyone forgot Snowden?) and raging wars without end in sight is the country pretending to be for democracy. This only tells me that the only greatness we still have in the West is the ability to spread propaganda. Somehow, people can be easily convinced that all this is for the greater good.
