As long as China holds on USA in SCS, more and more countries will come to help China. Europe, Russia, even India and Japan will help China publicly or stealthily. Japan gains more and more independence from USA with China-USA. All of these countries want China to drag on USA so that they can gain freedom from US control or pressures.
ISIS is created by USA. Since USA cannot hold on Mid-East, USA doesn't want major powers of IRan, Russia to fill the vacuum. ISIS's job is simply to keep the mid-east from other powers for USA so that USA can shift its power to take on China. But Putin forms Russia-IRan-Syria alliance and determine to fill the vacuum. Now USA is really having headache now. It is considering to take on ISIS by ground forces to avoid Russia take-up. USA war on two fronts is really crazy. Only inexperienced president such as Obama can do it.
Obama has no business sense, no executable strategy. From domestic healthcare, debt reduction to foreign policy, nothing has a solid strategy.
