Iran has a chance to help end the conflict in Lebanon by not reacting to the death of Hezbollah leader Hassan Nasrallah. Israel's airstrike weakened Hezbollah, which is a key part of Iran's influence in the region. Iran's response is crucial as there are talks about Nasrallah's cousin possibly taking over. President Pezeshkian wants to avoid a bigger war and focus on improving Iran's economy and rebuilding relations with the U.S. If the U.S. re-enters the Iran nuclear deal and lifts some sanctions, it could strengthen Pezeshkian against more hardline leaders and improve Iran-U.S. relations, which would be a positive step for peace in West Asia.
