The Joint Chiefs of Staff released this military strategy document in June 2015; this strategy was updated previously in 2011. The 2015 document focuses on countering violent extremist organizations.
In the introduction, chairman of the Joint Chiefs of Staff, General Martin Dempsey, stated:
"Today’s global security environment is the most unpredictable I have seen in 40 years of service. Since the last National Military Strategy was published in 2011, global disorder has significantly increased while some of our comparative military advantage has begun to erode. We now face multiple, simultaneous security challenges from traditional state actors and transregional networks of sub-state groups – all taking advantage of rapid technological change. Future conflicts will come more rapidly, last longer, and take place on a much more technically challenging battlefield. They will have increasing implications to the U.S. homeland....
"This 2015 National Military Strategy addresses the need to counter revisionist states that are challenging international norms as well as violent extremist organizations (VEOs) that are undermining transregional security. We are working with allies and partners to deter, deny, and – when necessary – defeat potential state adversaries. Concurrently, we are leading multiple coalition efforts to disrupt, degrade, and defeat VEOs. Central to these efforts is strengthening our global network of allies and partners. This integrated strategy requires us to conduct synchronized operations around the globe, implement institutional reforms at home, and sustain the capabilities, capacity, and readiness required to prevail in conflicts that may differ significantly in scope, scale, and duration."
