An Israeli attack on southern Beirut has intensified tensions across the Middle East, with analysts warning it could severely undermine ongoing efforts toward a potential agreement between the United States and Iran. Sami Nader, director of the Levant Institute for Strategic Affairs, described the strike as a critical test for US-Iran negotiations, noting that Israel seeks to keep the Hezbollah conflict separate from the talks while Iran insists on linking the two issues.

In an interview with Al Jazeera, Nader said Israel is pushing to isolate the Hezbollah front from diplomatic discussions, whereas Iran views the connection as essential to advancing any deal. He added that the incident could completely derail the potential agreement. Nader also pointed to Israel’s internal political dynamics, where right-wing factions have criticized Prime Minister Benjamin Netanyahu for not taking a tougher stance against Hezbollah and for aligning with US President Donald Trump’s position on avoiding escalation in Lebanon.

Analysts believe Iran’s response to the Beirut strike will determine whether regional tensions escalate further or if diplomatic channels remain open.
