U.S.-Iran Tensions Persist Over Nuclear Inspections Amid 60-Day Peace Roadmap

Diplomatic friction has emerged between the United States and Iran over the specifics of nuclear oversight, even as the two nations implement a new 60-day roadmap toward a final peace accord. While Vice President JD Vance reported significant progress in Switzerland, claiming Tehran had agreed to nuclear inspections, Iran’s Foreign Ministry explicitly denied making any new pledges. Despite this rift, the U.S. Treasury has issued a temporary sanctions waiver allowing Iran to sell oil in U.S. dollars, and lead negotiator Mohammad Bagher Qalibaf confirmed the upcoming release of $12 billion in frozen Iranian funds. On the operational front, a new communication hotline for the Strait of Hormuz has facilitated the passage of 24 commercial ships in the last 24 hours. However, the regional ceasefire remains fragile. Iran is reportedly using the current Memorandum of Understanding to pressure the U.S. into forcing an Israeli withdrawal from southern Lebanon. Meanwhile, President Trump has issued a stern warning that the U.S. maintains the capability to reinstate a blockade of the Strait within 30 minutes should Iran violate the terms of the developing agreement. The conflict remains in a state of delicate balance, with economic incentives driving negotiations against a backdrop of continued military posturing. While technical oversight committees are now active in Switzerland, the persistence of hostilities between Israel and Hezbollah threatens the 'ceasefire on all fronts' intended to underpin the diplomatic roadmap.
