If I was high up in Chinese military considering military action with taiwan, I would seriously consider Japan first strike. Why? Simply put you destroy Japanese and American naval bases including 7th fleet while in port your chances of victory with Taiwan and Japan double while taking out regional enemies with little loss compared to battle at sea. Also reminding America and Europe of difficulties of replying in time by sending their navies for support to region would take weeks from mainlands which China would be ready for by then. From there they cut off supply ships straight through island chain to Australia strangling Asian countries from food, fuel and etc etc. Making whole area weak and defenseless. Now China has control from mainland through to south pole. Any thoughts. Mean time Russia and Iran see window of opportunity thus results in ww3.
