"This report presents background information and issues for Congress on the overarching U.S. foreign policy issue of the U.S. role in the world. Certain statements and actions from the Trump Administration have led to uncertainty about the Administration's intentions regarding the future U.S. role, and have intensified an ongoing debate among foreign policy specialists, strategists, policymakers, and the public about what that role should be. Decisions that Congress makes about the U.S. role could have substantial or even profound implications for U.S. foreign policy, national security, and international economic policy, for Congress as an institution, and for many federal policies and programs."
