E Studies and Reports 1041. Report on highest-priority roles and missions of the Department of Defense and the Armed Forces (a) Sense of Senate It is the sense of the Senate that— (1) the National Defense Strategy correctly characterizes the leading strategic challenges facing the United States as the reemergence of great power competition, the erosion of the United States military technological advantage, enduring violent extremism and instability in the broader Middle East and Africa, and continued uncertainty in the United States about the availability of sufficient resources for national defense; (2) the National Defense Strategy correctly prioritizes the development of a more lethal joint force that is ready to deter and, if necessary, defeat aggression by great power competitors with advanced military capabilities, while conducting counterterrorism operations in a more sustainable manner, together with allies and partners; (3) the National Defense Strategy, and the implications of the Strategy for the size, structure, shape, roles, missions, and employment of the joint force, was not completed in time to inform fully the budget of the President for national defense for fiscal year 2019; (4) many Department of Defense programs of record are upgraded replacements of legacy systems that were not premised on the assumption that future conflict could occur in highly-contested environments against militarily advanced near-peer rivals
