Tensions Escalate as Trump Rejects Iranian Peace Terms and U.S. Strikes Tankers

Diplomatic efforts to resolve the U.S.-Iran conflict reached a critical impasse on May 13, 2026, as President Donald Trump labeled Tehran’s latest peace proposal "completely unacceptable" and "garbage." Speaking en route to a summit in Beijing, Trump emphasized that the U.S. blockade is successfully strangling Iran's economy and dismissed the need for external mediation, even as China tasked Pakistan with facilitating the reopening of the Strait of Hormuz. Iranian officials countered by blaming "maximalist" U.S. demands for the deadlock and signaled they could increase uranium enrichment to 90% if hostilities continue to escalate. On the ground, the military conflict intensified with U.S. forces targeting Iranian oil tankers in the Gulf of Oman. Regional instability spread as Kuwait reported thwarting an Iranian-linked infiltration attempt and the UAE expanded its sanctions against Hezbollah-affiliated entities. Israel has expressed concern that any potential diplomatic breakthrough might result in a "bad deal" that fails to fully dismantle Iran's nuclear infrastructure. Meanwhile, satellite imagery confirmed a total halt in shipments from Iran's primary export terminal, though Tehran is reportedly attempting to bypass the naval blockade through overland energy deals with neighboring Iraq and Pakistan. The economic toll of the conflict continues to mount, with U.S. war spending now estimated at $29 billion. Global energy markets remain volatile; Brent crude prices settled near $107 per barrel, dropping slightly as investors weighed the possibility of a ceasefire against a fourth consecutive week of declining U.S. inventories. Although China is positioning itself as a broker ahead of the upcoming summit, the U.S. administration maintains that the Strait of Hormuz—a vital global energy artery closed since early February—is likely to remain shut for several more weeks.
