On January 27, 2017, President Donald Trump directed Secretary of Defense James Mattis to initiate a new Nuclear Posture Review (NPR). The President made clear that his first priority is to protect the United States, allies, and partners. He also emphasized both the long-term goal of eliminating nuclear weapons and the requirement that the United States have modern, flexible, and resilient nuclear capabilities that are safe and secure until such a time as nuclear weapons can prudently be eliminated from the world.The United States remains committed to its efforts in support of the ultimate global elimination of nuclear, biological, and chemical weapons. It has reduced the nuclear stockpile by over 85 percent since the height of the Cold War and deployed no new nuclear capabilities for over two decades. Nevertheless, global threat conditions have worsened markedly since the most recent 2010 NPR, including increasingly explicit nuclear threats from potential adversaries. The United States now faces a more diverse and advanced nuclear-threat environment than ever before, with considerable dynamism in potential adversaries' development and deployment programs for nuclear weapons and delivery systems.

In late 2015, the People's Liberation Army (PLA) initiated reforms that have brought dramatic changes to its structure, model of warfighting, and organizational culture, including the creation of a Strategic Support Force (SSF) that centralizes most PLA space, cyber, electronic, and psychological warfare capabilities. The reforms come at an inflection point as the PLA seeks to pivot from land-based territorial defense to extended power projection to protect Chinese interests in the "strategic frontiers" of space, cyberspace, and the far seas. Understanding the new strategic roles of the SSF is essential to understanding how the PLA plans to fight and win informationized wars and how it will conduct information operations.

After summarizing the assumptions and evaluative methodology behind mainstream strategic theory, the study describes the current decentralized command and control system that, under conditions of surprise attack, could be unable to communicate with decision makers or with units responsible for executing the decisions.

Reviews status and theory of U.S. nuclear capabilities. Focuses on military commitments, principle of strategic deterrence through mutual assured destruction, and the need for development of countervailing weapons systems to maintain favorable U.S. balance of power in face of increased Soviet nuclear strike capabilities.
