European business, markets and politics
During a stop at his Doonbeg resort, Trump combined golf, geopolitics and business promotion, sparking controversy on several fronts.

Donald Trump addressed reporters from the Doonbeg golf resort on Ireland's west coast on Sunday, using the platform to attack critics of artificial intelligence, urge Ukrainian President Volodymyr Zelensky to stop targeting Russian diesel refineries, and float the idea of a united Ireland.
The former president’s comments intertwine three sensitive issues. By branding AI sceptics as "negative forces", he aligns himself with industry voices defending rapid development, a stance echoed in recent debates such as those covered by Anthropic's defence of AI safety records. His plea to Zelensky, "let him go after targets, but not diesel fuel", touches on the ongoing Russia‑Ukraine war and could be read as a push to ease fuel shortages that have driven up oil prices in the United States and Europe.
Adding to the diplomatic mix, Trump told Irish prime minister Micheál Martin that he would "love to see" a united Ireland, suggesting the historic split between the Republic and the United Kingdom could be resolved "now". The remark broke with the traditional US stance of neutrality on the issue and provoked immediate pushback from unionist politicians in Northern Ireland.
The president’s visit coincided with the final round of the Irish Open, where Irish star Shane Lowry led the field. Trump, who owns the Trump Organization course since 2014, walked onto the first tee to a cheering crowd before presenting the trophy to the winner later in the day.
"I would love to see a united Ireland, it may as well happen now," Trump said.
Accompanying him were his sons Eric Trump and Donald Trump Jr., who have been running the family business while their father occupies the White House. Security costs for the weekend topped €20 million, with roughly 4,000 Irish and U.S. officers deployed, including anti‑drone measures. About 30 locals protested, accusing the president of supporting policies they deem harmful.
Trump’s remarks are likely to reverberate in several arenas. In Washington, Democrats may use the episode to amplify concerns over potential conflicts of interest, especially as the president prepares to host the G20 summit at his Miami resort later this year. In Europe, the united‑Ireland comment could stir diplomatic chatter between Dublin, London and Brussels, while his AI stance may embolden industry groups lobbying against stricter regulation.
For markets, any shift in the narrative around Russian diesel production could influence fuel pricing ahead of the U.S. mid‑term elections, while heightened scrutiny of the president’s business ties may affect investor sentiment toward his domestic ventures.
