How should New Zealand health professionals respond to Trump 2.0?

Donald J Trump began his second term as president of the United States (US) in January 2025. Since then, his administration has abandoned the precedents necessary for good government, brushed aside restrictions on executive power, sacked tens of thousands of federal workers and undermined healthcare within the US and overseas. I argue the consequences of Trump's actions are so serious they must concern health professionals everywhere, and outline three ways to respond. These are: to actively and effectively support colleagues in the US; to do what we can to sustain health gains worldwide; and to oppose health-damaging Trump-like thinking in Aotearoa New Zealand.
