I still have strong believing of US system. We shouldn't focus on how Xi is doing with his policy in China. I think what he is doing will soon to make messes in China. In other words, sooner or later, Xi is going to face big challenge domestically. What we need to prevent is to lessen the impact once China is in economic trouble. We also need to be watchful on China's strategy to make US more divided. Our disadvantage is we, as a relatively open society, are easily to be penetrated by non-conventional war.
