Global politics is being pulled in several unstable directions at once. Donald Trump says the month-old U.S.-Iran ceasefire is on “life support” after dismissing Tehran’s latest proposal, underscoring how far the two sides remain from a durable deal and raising fresh concerns about shipping through the Strait of Hormuz. At the same time, Trump is preparing for a very different diplomatic test in Beijing, where he will arrive alongside a high-profile roster of U.S. chief executives including Elon Musk and Tim Cook for talks with Xi Jinping aimed at unlocking commercial agreements. In Britain, Prime Minister Keir Starmer faces a mounting revolt inside Labour, with more than 50 MPs now reportedly urging him to resign after a speech meant to restore his authority instead deepened the crisis. Beyond Westminster and Washington, officials in France are managing a confirmed hantavirus case linked to a cruise ship outbreak.
