Future A2/AD challenges are part of a security environment that will be characterized by increasing complexity, uncertainty, and rapid change, according to DOD. Further, national security challenges will continue to arise from ongoing concerns such as violent extremism, the proliferation of weapons of mass destruction, resource competition, and the rise of modern competitor states, among others. These concerns, according to DOD, combined with the proliferation of advanced technologies; the increasing importance of space and cyberspace; and the ubiquity of digital networks, including social media, will make the future security environment less predictable, more complex, and potentially more dangerous than it is today.
