Behind the US-Iran deadlock: Did Netanyahu's call to Vance play a role in derailing talks?

The high-stakes talks between the United States (US) and Iran in Pakistan's capital of Islamabad, aimed at easing tensions in the Middle East and open the Strait of Hormuz, failed on Sunday, leading to an uncertainty on what will happen next. As the two sides failed to arrive on a consensus, US Vice President JD Vance said Washington gave its 'final and best' offer, but the Iranians were unwilling to accept it.
