- Defiance. Benjamin Netanyahu declared on 15–16 June that Israeli forces will remain in southern Lebanon, Syria, and Gaza “for as long as necessary,” directly contradicting the terms of the US-Iran memorandum of understanding that calls for an end to the Lebanon conflict.
- Scope. The IDF now occupies approximately 570 square kilometres of southern Lebanese territory, roughly 10 km deep, and has published expanded maps of its “security zone.”
- Diplomatic pressure. Iran has warned of a “harsh response” if Israeli strikes continue, while the Trump administration has not yet leveraged military aid to press Israel toward withdrawal.
Hours after the US-Iran deal was announced, Israeli Prime Minister Benjamin Netanyahu convened a televised press conference on 16 June 2026 and stated that his government would not withdraw troops from any of the three fronts where the IDF is currently deployed. “We will restore security and prosperity to northern towns,” Netanyahu said. “That requires maintaining the security zone in southern Lebanon; it requires that we not leave there, as long as Israel’s security needs require it.”
What the MoU says—and what Israel rejects
The US-Iran memorandum of understanding, virtually signed on 19 June at the Bürgenstock resort after a last-minute delay to the planned in-person ceremony, includes a 60-day ceasefire framework and calls for an end to active hostilities in Lebanon. A senior White House source confirmed that an IDF withdrawal from Lebanon is not explicitly required under the MoU’s first-phase terms. Netanyahu is nonetheless bracing for US pressure over the Lebanon campaign as the follow-on negotiations begin.
Defence Minister Israel Katz reinforced Netanyahu’s position, stating the government is “pursuing a clear policy under which the IDF will remain in the security zones for an unlimited period of time” to protect Israeli communities from “jihadist elements.” Katz separately warned Iran against attacking Israel over its continued Lebanon operation, threatening “full force” retaliation.
The Lebanon front
Israel began ground operations in southern Lebanon in early March 2026, following Hezbollah’s rejection of an earlier ceasefire proposal. IDF strikes continued in Lebanon as recently as 18 June, with at least three deaths recorded that day according to Arab News. The IDF published an expanded operational map showing its footprint across the southern Lebanese territory it designates a security buffer.
Iran has linked the Lebanon question to the broader US-Iran framework. Iranian officials maintain that Israeli withdrawal from Lebanon is essential to any durable settlement, and Tehran’s military has issued warnings that continued Israeli strikes will draw a response. The gap between those Iranian demands, US diplomatic aims, and Israeli military posture represents the most significant unresolved variable in the post-MoU landscape.
Washington’s leverage question
Analysts and European officials have noted that the Trump administration holds significant leverage over Israel through military aid and diplomatic cover at the UN—tools it has not yet deployed on the Lebanon question. Whether that changes as the 60-day negotiating window progresses will shape whether the Lebanon ceasefire survives or becomes a second active front in the broader regional settlement talks.
