Jacinda Ardern has re-entered the political fray with a rallying call for internationalism, rebuking the inward outlook of the United States under President Donald Trump.
The popular former New Zealand prime minister spoke at Yale College's Class Day on Monday (Australian time), the undergraduate arm of the prestigious Ivy League university.
Dame Jacinda, who has lived in the US as a Harvard-based fellow since late 2023, said she opted against "the usual pep talk that perhaps you might expect" in an address witnessed by thousands.
