China has the manpower and the firepower to deal with terrorism in the middle east. US military forces are already stretched thin. The war against ISIS and terrorism needs to be a global affair - not just one led by the United States. This is a positive development.
Israel, Turkey, (Parts of Iraq) and Saudi Arabia are under NATO/Western spheres of influence. Iran,the Assad Regime and Iraq are firmly under Russian influence (and indirectly, China and Brazil). Proxy lines have been drawn much in the way of the Cold War.
