U.S.-Iran Conflict: Trump Asserts ‘Total Control’ of Hormuz as Regional Allies Warn of Escalation Risk

The U.S.-Iran conflict has entered a new phase of intense diplomatic and military pressure. President Donald Trump, in a video address on May 21, declared that the U.S. naval blockade of Iran is '100% effective' and claimed that the U.S. military has 'wiped out' the Iranian navy and decimated 85% of its missile capacity. These claims come as the U.S. reportedly utilized roughly 200 THAAD interceptors to defend against previous Iranian strikes. Despite these declarations of dominance, senior Iranian sources indicate that diplomatic back-channels remain open, suggesting that while no formal agreement has been signed, the technical gaps between Washington and Tehran are narrowing. The regional and international fallout of the conflict is expanding. In the Gulf, UAE foreign-policy adviser Anwar Gargash warned that further escalation could have dire consequences for regional stability. Simultaneously, the conflict is straining transatlantic relations. Secretary of State Marco Rubio is expected to deliver a sharp rebuke to NATO ministers, conveying President Trump’s disappointment with the alliance's limited involvement. Reports suggest the President has even raised the possibility of a U.S. withdrawal from NATO over the issue. On the military front, Israel continues to target Iranian-linked proxies. The IDF recently conducted an airstrike on a Hezbollah weapons-production facility concealed beneath a civilian clinic in Tyre, Lebanon. According to the Israeli military, the site was a launch point for missiles directed at Israel. As the Israel-Hezbollah front remains active, the U.S. maintains its 'maximum pressure' stance, with President Trump emphasizing that no ships are permitted to enter or exit Iranian waters without American approval.
