U.S. and Iran Move Toward Peace Deal Amid Legislative Pushback and Regional Tensions

Iranian President Masoud Pezeshkian has arrived in Islamabad to engage in critical mediation with Pakistani Prime Minister Shehbaz Sharif. This visit comes as the United States and Iran move closer to a permanent peace agreement, with U.S. Vice President JD Vance stating that a "solid foundation" for a final deal has been established following diplomatic talks in Switzerland. The emerging framework includes the return of International Atomic Energy Agency (IAEA) inspectors to Iran to monitor the permanent cessation of its nuclear weapons program. However, the peace process faces significant internal and regional friction. In Washington, the U.S. Senate passed a War Powers Resolution in a 50-48 vote, marking the first formal congressional check on President Trump’s military authority regarding Iran. Concurrently, the Iranian parliament has voted to push for the closure of the Strait of Hormuz, a vital global energy corridor, in response to previous U.S. airstrikes on Iranian nuclear facilities. This legislative move threatens to disrupt global oil markets and reverse recent maritime concessions. Regional allies are also reacting to the shifting landscape. Israeli Prime Minister Benjamin Netanyahu is reportedly under significant pressure as Israel has been excluded from the current security memorandum between Washington and Tehran. While diplomatic efforts continue, violence flared in Lebanon on Tuesday, illustrating the fragility of a proposed "deconfliction cell" between Israel and Hezbollah. Additionally, the U.S. issued a mixed signal by denying visas to Iran’s 15-member World Cup delegation while easing travel restrictions for the players themselves.
