Memorandum for All Department of Defense Personnel: Guidance from Secretary Jim Mattis [open pdf - 820KB]
"The start of a new fiscal year serves as an opportunity for greater alignment as we reconfirm our commitment to the America. As a member of the U.S. Department of Defense, you play a vital role in supporting the three million men and women - uniformed and civilian - who fight for our Nation's interests abroad. We protect and defend the Constitution, our people, and our values, and America's military reinforces traditional tools of diplomacy, ensuring President Trump and our diplomats negotiate from a position of strength. We are a Department of war. We must be prepared to deal with an increasingly complex global security situation, characterized by an accelerating decline in the management of the rulesbased international order. North Korea's provocative actions and reckless rhetoric continue despite United Nation's censure and sanctions. Russia has violated the borders of nearby nations and seeks veto power over the economic, diplomatic, and security decisions of its neighbors. China is a long-term strategic competitor that seeks to intimidate its neighbors while escalating tensions in the South China Sea. Iran continues to sow violence and remains the largest long-term challenge to Middle East stability. Despite recent gains against ISIS, terrorist groups continue to murder the innocent and threaten peace."
