U.S.-Iran Conflict Escalates as Trump Ends Ceasefire; Tehran Threatens Hormuz Closure

The conflict between the United States and Iran has entered a volatile new phase following President Trump’s declaration that the June memorandum of understanding is now void. Within the last 24 hours, the U.S. military launched a second wave of airstrikes targeting 90 sites, prompted by what the administration describes as necessary retaliation for attacks on commercial vessels. In response, Iran has warned it will immediately close the Strait of Hormuz to all traffic if the U.S. continues its military campaign, a move that has spiked global oil prices above $80 per barrel and elevated maritime shipping risks to the highest level. The theater of war has expanded significantly into the maritime domain, with regional officials reporting 50 incidents in recent weeks, including three commercial vessels targeted within the last few days. While the Trump administration, supported by Vice President JD Vance, maintains that military force was the only remaining option, the President has signaled that diplomatic negotiations could still proceed during the NATO summit in Turkey. However, Iranian officials are reportedly seeking to broaden the conflict by coordinating with regional allies in Lebanon and urging unity against Israel. The humanitarian and economic implications of the ceasefire's collapse remain uncertain as global leaders call for de-escalation. NATO Secretary General Mark Rutte has voiced support for the U.S. strikes as 'absolutely necessary,' yet fears of a prolonged interruption to global supply chains persist. Iran’s current retaliatory strategy, which involves targeting twice as many sites as the U.S. hits, threatens to further destabilize infrastructure across the Gulf, including in nations such as Bahrain and Kuwait.
