Analysis: Will Lebanon remain a battlefield, bargaining chip despite U.S.-Iran deal?

BEIRUT, Lebanon, June 19 (UPI) -- The Iran war may be over, but southern Lebanon is likely to remain a battlefield and a bargaining chip in regional negotiations, despite Lebanon's inclusion in the memorandum of understanding between Iran and the United States -- a provision Israel rejected to preserve its freedom of action against Hezbollah, analysts said.

Violence in southern Lebanon subsided after the United States and Iran announced a 14-point preliminary agreement to end hostilities, reopen the Strait of Hormuz, and begin nuclear talks under a 60-day extended ceasefire.

The MOU was signed remotely on Wednesday by U.S. President Donald Trump and Iranian President Masoud Pezeshkian, two days ahead of a formal signing ceremony scheduled to take place in Switzerland.

Rather than a cessation of hostilities, southern Lebanon witnessed a sharp escalation in fighting, with Israel intensifying its airstrikes and Hezbollah targeting Israeli forces seeking to seize the strategic Ali Taher hill in the Nabatiyeh district. Both sides traded accusations of violating the ceasefire established under the MOU.

The overnight exchange left 47 people dead, including women and children, and 97 others wounded in Israeli strikes on several areas of Lebanon, including Nabatiyeh and the eastern Bekaa Valley. Four Israeli soldiers, including a lieutenant colonel, were also killed by Hezbollah fire.

Israeli airstrikes continued beyond a new ceasefire between Israel and Hezbollah, brokered by the United States and Qatar with Iranian assistance, and set to take effect at 4 p.m. Friday.

It remains to be seen how long this new truce will last, as is the case with the U.S.-Iran ceasefire, given ambiguities in the MOU and differing interpretations of its clauses.

Israel, which rejected Trump's "betrayal" and the agreement with Iran, is seeking to change the arrangement by force in order to preserve its freedom of action against Hezbollah threats in southern Lebanon. It also seeks to maintain control of a security zone in southern Lebanon and is not willing to withdraw its forces unless its northern region is secured and safe.

Riad Tabbarah, Lebanon's former ambassador in Washington, said Israel believes it has the right, as it usually does, to modify the agreement on the ground after "accepting it on paper, so as not to annoy Trump."

"This is exactly what they did last time, and what they do every time," Tabbarah told UPI. "Today, they are doing the same."

He was referring to the Nov. 27 ceasefire agreement brokered by the United States and France to halt the war that began when Hezbollah opened a support front for Gaza on Oct. 8, 2023.

Despite the truce, Israel continued to carry out strikes against Hezbollah, which refrained from retaliation for 15 months as it sought to reorganize its ranks before resuming fighting on March 2 in support of Iran.

The March escalation increased the human and material toll in Lebanon after Israel applied what was described as a "scorched earth" policy to empty border areas of residents and render them uninhabitable.

More than 3,980 people have been killed and 12,001 injured in the past 109 days, with 1.2 million displaced under Israeli evacuation orders. Large areas were devastated, including the complete destruction of 70 villages and heavy damage to infrastructure.

It would be "pure imagination and illogical" to think that Israel would easily withdraw and relinquish the security zone it is building in southern Lebanon, intended to prevent anyone from crossing its border and carrying out kidnappings like Hamas did from Gaza on Oct. 7, 2023, according to Tabbarah.

What could stop the frustrated Prime Minister Benjamin Netanyahu from sabotaging Trump's efforts to finalize a lasting peace deal with Iran and continuing his military campaign in Lebanon?

The tension between Trump and his administration on one side, and Netanyahu and his government officials on the other, over the Iran deal "is growing, and we need to wait and see how it will develop," said Lebanese former foreign minister Fares Boueiz.

As for Iran, Boueiz noted that as long as it believes it is benefiting from the deal with Trump, it "won't do anything to jeopardize the understanding."

"It is clear that the U.S.-Iran war is over, with no winner and no loser and no complete victory for anyone," he told UPI. "The next 60 days will determine whether a final agreement is reached and whether Netanyahu will be able to obstruct it."

The fear that Lebanon remains an open battlefield and a bargaining chip has grown, despite Iran's pledge to Hezbollah that it will not proceed with the MOU talks if Israel fails to observe a full ceasefire in Lebanon and withdraw from the southern region.

Lebanese retired Maj. Gen. Abdul Rahman Chehaitli argued that the war in south Lebanon was "an Iran-Israel war sponsored by the U.S."

"Now that Iran has reconciled with the U.S., signed an agreement, and is negotiating, the battle is over for them," Chehaitli said in an interview with UPI. "This means that Lebanon should work toward a solution with Hezbollah and engage in serious negotiations to secure Israel's withdrawal and end any illegitimate armed presence."

Lebanon, which opted for U.S.-mediated direct talks with Israel to end the war despite Hezbollah's objections, is preparing for another round of diplomatic talks with Israel scheduled to take place in Washington next week.

While Hezbollah leader Sheikh Naim Qassem has set new terms for the talks, saying they should be limited to "mutual security," Israel is insisting on disarming the Iran-backed group and keeping it away from its borders.

Hezbollah has also been pushing to drop the Lebanon-Israel direct negotiations in favor of the U.S.-Iran track.

"Hezbollah can say whatever it wants, but Lebanon should negotiate on its own," Chehaitli said, adding that the militant group "is concerned about the day after, seeking security guarantees or immunity."

Lebanon has no option but to negotiate its way out of the war, but the process will be long, and southern Lebanon will remain under Israeli fire and a bargaining chip in Iran's hands until a final deal with Washington is reached, according to some analysts.

Tabbarah argued that Israel did not go through all this war only to back down, while Iran seeks a high price in return for Hezbollah and its other regional armed proxies.

"I don't think Iran will go to war again. It will find a formula to save face for its armed militias," he said, adding that the U.S., on its part, will have to restrain Israel and force Netanyahu to accept a full ceasefire in Lebanon.

He explained that a decision by Trump to stop U.S. military assistance to Israel, or "anything of the sort," would be a serious step.

Tabbarah, however, warned that the solution "is not for tomorrow unless Israel drops its dream of establishing Greater Israel."
