Americans debate how engaged the U.S. should be globally. Some advocate 'America First' policies focused on domestic priorities, while others argue international engagement protects American interests and values. Challenges include managing relationships with China and Russia, supporting allies in Europe and Asia, addressing terrorism and nuclear proliferation, and determining when and how to use military force. In the Trump second term these debates have sharpened: the administration has used economic pressure on allies (including tariff threats over Greenland), reshaped U.S. policy on Ukraine and the Middle East, and conducted direct military action in Venezuela. With ongoing conflicts and great-power competition, these questions have real consequences.
