U.S.-Iran Peace Talks Move to Pakistan Amid Domestic War Powers Constraint

Negotiations to end the conflict between the United States and Iran have entered a pivotal phase following Iranian President Masoud Pezeshkian’s arrival in Pakistan. This diplomatic shift follows recent high-level talks in Switzerland where Vice President JD Vance confirmed a "foundation" for a final deal was established. The emerging framework includes provisions for a permanent nuclear monitoring program via the IAEA and the reopening of the Strait of Hormuz, a vital lane for global oil traffic that has been disrupted by the conflict. The diplomatic momentum faces significant domestic and regional pressure. In Washington, the U.S. Senate passed a bipartisan war powers resolution in a 50-48 vote, signaling a congressional effort to limit President Trump’s ability to take further military action without oversight. Four Republicans joined the majority, reflecting internal party divisions over the administration's interventionist strategy. Meanwhile, Israeli Prime Minister Benjamin Netanyahu is facing increased pressure to avoid actions that might jeopardize the deal, as Tehran warns that Israeli military moves are a primary threat to the peace framework. On the ground, the path to de-escalation remains fragile. A two-day streak of ceasefire in Lebanon was broken by renewed violence on Tuesday, hindering efforts to create a "deconfliction cell" to manage fighting between Israel and Hezbollah. Iranian officials have emphasized that the success of the peace roadmap depends on strict adherence to the agreed text, warning against statements or actions that fall outside the negotiated obligations.
