The year 2016 is an eventful year as well as an important turning point in the world order. The uncertainty about international military dynamics is rising. The major powers are speeding up strategic adjustment in a bid to gain military superiority over others. Tackling traditional security issues remains top of the agenda. Both the United States and Russia put priority on addressing strategic competition and potential conflicts between great powers. The rapid development of technology and equipment is ushering in a new round of worldwide military revolution. New sectors have become an important ground for military contestation. The great power game in new sectors is all fired up. The spillover effects of military conflicts on politics and economy is becoming more and more obvious，especially in the case of conflicts between the Middle East and Europe. The international system and its structure and the nature of international relations are undergoing major changes. The old world order is defunct and collapsing，unable to provide states with security and prosperity and not going to take a turn for the better. In the transition period，all countries，even the major powers，need to redefine their status. The relationship between countries is more complex. Although the world system at large is in a state of dynamic balance，it is also enmeshed in conflicts，disputes and turbulence.
