The Pentagon's Joint Staff recently released its "Joint Operating Environment 2035," a document "designed to encourage the purposeful preparation of the Joint Force to effectively protect the United States, its interests, and its allies in 2035."
Further:
This document describes the future security environment and projects the implications of change for the Joint Force so it can anticipate and prepare for potential conflicts. To do this, Section 1 describes the circumstances that are likely to alter the security environment. Next, Section 2 explores how the intersection and interaction of these changes might impact the character of war in the future. Finally, Section 3 provides a framework to think about the full range of Joint Force missions and how they may evolve over time.
