The 10-day-old ceasefire between the United States and Iran is on the verge of collapse following the most significant military escalation since the June 17 Memorandum of Understanding was signed. On June 26, U.S. Central Command (CENTCOM) conducted precision airstrikes against Iranian coastal radar positions and drone storage sites on Sirik and Qeshm islands. The Trump administration stated these strikes were a direct response to an Iranian-backed attack on the Singapore-flagged vessel Ever Lovely in the Strait of Hormuz. In immediate retaliation, the Islamic Revolutionary Guard Corps (IRGC) announced it had targeted U.S. military installations in the region, characterizing the American kinetic response as a "blatant violation" of international law. The escalation has broadened to include drone activity in the Strait, where President Trump confirmed that Iranian drones successfully damaged a commercial vessel despite U.S. interceptions. Iranian officials have also issued warnings to neighboring Gulf states, demanding they refuse the use of their territory for U.S. military operations. The instability is vibrating across the Middle East, with Kuwaiti air defenses intercepting potential threats and continued fighting between Hezbollah and Israeli forces in Lebanon. The primary concern for global markets remains the safety of the Strait of Hormuz, a critical energy transit point. While both Washington and Tehran have utilized diplomatic back-channels in recent weeks, the return to direct military strikes suggests a breakdown in the trust required to maintain the interim peace deal.
