Switzerland – President Donald Trump has publicly threatened to launch “harder” military strikes on Iran than those carried out “last week” if Tehran does not immediately curb its proxies in Lebanon, according to a Truth Social post issued during negotiations in Switzerland. The message, which demands that Iran stop “highly paid PROXIES in Lebanon from causing trouble,” lands as U.S. officials work with counterparts from Pakistan and Qatar to preserve a fragile ceasefire. Trump’s language highlights the possibility of renewed, large-scale military action even as his administration’s delegation participates in high-level diplomacy at the Burgenstock resort. Switzerland – The President’s ultimatum directly undercuts Vice President JD Vance, who is leading the U.S. delegation at the summit and has cast the talks as a “historic moment” and a chance to “turn over a new leaf” in the region. The sharp contrast between Trump’s public threats and Vance’s diplomatic outreach has injected uncertainty into the U.S. negotiating position and complicated efforts to stabilize the ceasefire. Officials at the Switzerland summit are now trying to reconcile the President’s statements with ongoing technical discussions, while Iran’s delegation has not yet issued a formal response, heightening tensions around the talks and drawing scrutiny from international observers and markets.
