Trump called Netanyahu on June 1 in what two US officials and a third source briefed on the call described to Axios as an expletive-laden confrontation. Trump told Netanyahu, "You're fucking crazy", demanded he scale back Lebanon operations, and accused him of ingratitude. A second source said Trump yelled, "What the fuck are you doing?" Trump felt that Netanyahu's decision to escalate in Lebanon was disproportionate and directly threatening to collapse the Iran negotiations. The Beirut strikes Netanyahu had planned were called off following the call, with an Israeli official confirming to Axios that the strikes would not happen.
Netanyahu responded publicly by contradicting Trump's ceasefire announcement. In a statement, Netanyahu said the IDF would continue its operations in southern Lebanon "as planned" and threatened to strike Hezbollah targets in Beirut if the group didn't stop attacking Israeli towns. Defense Minister Israel Katz separately denied there was any ceasefire in Lebanon at all. Trump announced a ceasefire; Netanyahu said operations would continue. The split exposed the core disagreement: Trump wants the Iran deal to include a Lebanon ceasefire as part of a comprehensive regional settlement, and Netanyahu refuses to tie Israeli military options to any US-Iran diplomatic framework.
The political rift has deep structural roots for Netanyahu. His far-right coalition partners — National Security Minister Itamar Ben Gvir and Finance Minister Bezalel Smotrich — publicly declared they won't allow a peace deal with Iran that constrains Israeli military operations. Ben Gvir called any such proposal "an agreement that can harm the State of Israel." Netanyahu's coalition was already teetering, with ultra-orthodox parties declaring they had "no trust in Netanyahu" after he failed to pass military service exemption legislation. Elections were scheduled for October 2026, and polling published by Haaretz in late May 2026 showed 42% of Likud voters weighing or having already decided to back a different party.
The US-Iran nuclear deal framework in 2026 doesn't exist in a vacuum. The JCPOA — the 2015 deal negotiated by Obama with the P5+1 — limited Iran's uranium enrichment in exchange for sanctions relief. Netanyahu flew to Washington in March 2015 and addressed a joint session of Congress to oppose a sitting president's foreign policy, warning that "the deal with Iran is dangerous and will ultimately lead to war." Trump then withdrew from the JCPOA on May 8, 2018, calling it "the worst deal ever." Iran responded by stockpiling roughly 440 kilograms of highly enriched uranium — the exact proliferation problem Trump's 2026 MOU now tries to undo. Netanyahu opposed the 2015 deal and got the 2018 withdrawal; now he's trying to veto the 2026 successor.
The War Powers ResolutionA 1973 statute requiring the President to notify Congress of troop deployments and limiting combat operations to 60 days without congressional authorization.Key ConceptWar Powers ResolutionA 1973 statute requiring the President to notify Congress of troop deployments and limiting combat operations to 60 days without congressional authorization.Open concept was passed by Congress on November 7, 1973, over Nixon's veto, after Nixon secretly bombed Cambodia during the Vietnam War without notifying Congress. The House voted 284-135 to override — four votes more than the two-thirds required; the Senate voted 75-18. The resolution requires the president to notify Congress within 48 hours of committing armed forces and bars military operations from lasting more than 60 days without congressional authorization. Trump launched strikes on Iran on February 28, 2026, without seeking authorization, invoking Article II. The Trump administration then declared on May 1, 2026 that hostilities had "terminated," arguing the 60-day clock reset with the ceasefire — a legal maneuver no prior administration had attempted with this wording.
The US relationship with Lebanon through Israel carries its own history. In August 1982, US Marines entered Lebanon as part of a multinational force to oversee the Palestinian withdrawal. On October 23, 1983, a truck bomb killed 241 US military personnel in Beirut — the deadliest single-day death toll for the Marine Corps since Iwo Jima. Reagan ordered withdrawal on February 7, 1984, after waning congressional support. The bombing was attributed to elements that became Hezbollah, backed by Iran. That 1983 attack is the direct ancestor of the group Trump and Netanyahu were arguing about on June 1, 2026.
Iran's insistence on including Lebanon in any ceasefire reflects Hezbollah's role as Iran's most powerful regional proxy. Hezbollah chief Qassem stated on May 24, 2026 that the group's disarmament was "annihilation" and couldn't be accepted. Israel demands full Hezbollah disarmament as a condition for any durable ceasefire. The conflict in Lebanon had killed at least 2,489 people and injured 7,719 as of late April 2026, according to OHCHR, with over one million people displaced — more than 20% of the country's population.
The Senate advanced a War Powers Resolution on a 50-to-47 procedural vote to curb Trump's authority, with a handful of Republicans joining Democrats. The measure faces a near-certain veto by Trump and would require two-thirds majorities in both chambers to take effect. Congress rejected nine such measures since early March 2026. The pattern matches the WPR's entire history since 1973: every president has claimed it's unconstitutional, no court has enforced it, and the 60-day clock has never once been allowed to expire and trigger a withdrawal.
By the end of June 1, Trump announced on Truth Social that he'd spoken to both Netanyahu and, via intermediaries, to Hezbollah leaders, and claimed both sides had pledged to stop fighting. Hezbollah confirmed via the Lebanese Embassy in Washington that it agreed to a US proposal calling for a ceasefire — it would refrain from attacking Israel in exchange for Israel ceasing strikes on Beirut. Netanyahu's office simultaneously said southern Lebanon operations would continue. Trump called the Lebanon situation "a little glitch today" that he "turned around very quickly." The Soufan Center's June 1 intelligence brief found something structural: Israel escalated specifically to create pressure on the US-Iran talks, treating Lebanese operations as leverage against a deal it wasn't invited to shape.
