Donald Trump signs Iran memorandum and isolates Netanyahu
U.S. President Donald Trump has signed a preliminary memorandum with Iran that seeks to end the Iran war, reopen the Strait of Hormuz and create a 60-day window for a final settlement, according to U.S. officials and Pakistani Prime Minister Shehbaz Sharif. The agreement leaves Israeli Prime Minister Benjamin Netanyahu exposed: Israeli officials say he had not seen the final text, while U.S. officials say Israel was briefed on the substance. The most sensitive points are Lebanon, where the draft extends the halt in fighting to the Israel-Hezbollah front, and Iran's nuclear file, where U.S. officials say Tehran would at least down-blend highly enriched uranium under IAEA supervision. For Europe, the immediate issue is less Israeli coalition politics than whether the deal stabilises energy flows and revives enforceable nuclear monitoring after years of failed pressure, sanctions and military escalation.

Trump's America: From the First Term to Now
A living dossier on Donald Trump's political project, from the 2016 victory through the post-2020 contested period to his return to the White House in January 2025 — and the political, legal, economic and institutional consequences still unfolding.
About this story
Benjamin Netanyahu (Israel's prime minister, back in office since 2022) built his Iran policy around military pressure and deterrence. Donald Trump (U.S. president, in his second term) signed the memorandum during the G7 summit in France. Masoud Pezeshkian (Iran's president since 2024) is the Iranian signatory named by U.S. officials. Shehbaz Sharif (Pakistan's prime minister) presented Pakistan as a mediator alongside Qatar (Gulf state and frequent regional broker). Hezbollah (Iran-backed Lebanese armed movement and party) is central because the draft covers fighting in Lebanon. The Strait of Hormuz (narrow Gulf waterway between Iran and Oman) is the energy chokepoint the deal seeks to reopen. The International Atomic Energy Agency, or IAEA (UN nuclear watchdog in Vienna), would supervise uranium down-blending. The JCPOA (2015 Iran nuclear accord) is the benchmark for earlier nuclear limits and sanctions relief. Versailles (French palace near Paris) became the symbolic signing location.
How to read this story
The history
The EEAS states that the 2015 JCPOA was concluded by Iran, the E3/EU+3 and the EU to keep Iran's nuclear programme exclusively peaceful while lifting nuclear-related sanctions. Trump withdrew the United States from that framework in 2018 during his first term, and the later cycle of sanctions, enrichment disputes and armed escalation weakened European leverage. The new memorandum echoes earlier crisis diplomacy after the 2025 Israel-Iran ceasefire, but differs because U.S. officials say it links a regional halt in fighting, Hormuz reopening, nuclear talks and sanctions waivers in a single short timetable.
The geopolitics
The memorandum suggests Iran's strongest leverage was not battlefield victory but disruption risk around Hormuz. It also shows the limits of Israel's influence when Washington decides that energy stability and a negotiated nuclear pause matter more than continuing the campaign. The broader contest is over whether great-power pressure can still produce enforceable nonproliferation bargains.
Why now
The trigger is the signing of the U.S.-Iran memorandum on June 17, 2026, after weeks of secrecy over the text and pressure to reopen the Strait of Hormuz. Its Lebanon clause immediately turned the deal into a political problem for Netanyahu.
What to watch
Watch whether Hormuz traffic returns within the 30-day window described by U.S. officials, whether the 60-day talks produce a final text, whether the IAEA confirms access, and whether Israel treats the Lebanon language as binding in practice.
Local impact
The most local Belgian effect is in Brussels, where EU foreign-policy staff, NATO-linked officials, diplomats and energy-sector representatives will have to interpret a U.S.-Iran framework Europe did not control. The impact is analytical and institutional rather than street-level: it shapes briefings, contingency planning and energy-risk assessments more than daily public services.
International angle
The agreement sits at the intersection of U.S.-Iran diplomacy, Israeli security policy, Lebanese sovereignty, Gulf mediation and European energy exposure. For the EU, the issue is whether a U.S.-led memorandum can restore a verifiable nuclear track and stabilise shipping without giving Europe a formal seat comparable to its 2015 JCPOA role.
What this means for you
Belgian readers should expect no immediate domestic rule change, but fuel, freight and travel costs could respond quickly to confidence in Hormuz reopening. Businesses exposed to energy or shipping should track price volatility and insurer guidance. Policy readers should watch EU and NATO messaging from Brussels for signs of support, distance or contingency planning.
What happens next
U.S. officials said the parties have 60 days to negotiate a final agreement, potentially extendable by mutual consent. The immediate tests are whether Hormuz traffic normalises, whether Iran permits the promised nuclear handling under IAEA supervision, and whether Israel limits operations in Lebanon. A formal ceremony in Switzerland had been planned, but Pakistani messaging left some uncertainty over its necessity.
Potential consequences
If the memorandum holds, energy prices could ease and the EU may gain space to rebuild a nuclear-monitoring track from the sidelines. If it fails, Belgium and the wider eurozone could face renewed fuel-price pressure, while Israel may resume wider operations and Iran may use Hormuz leverage again. Netanyahu's domestic position could also weaken if Israeli voters judge that Washington ended the war on terms Israel could not shape.
Opposing perspectives
- Israeli government / Netanyahu camp
Israeli officials say Netanyahu was not shown the final text and argue that any Lebanon clause must not force Israel to withdraw while Hezbollah remains armed. Their strongest case is that a nuclear memorandum with Iran cannot bind Israel's security operations against a militia on its northern border.
- Trump administration
U.S. officials frame the memorandum as a way to stop a costly war, reopen Hormuz and test Iran's nuclear commitments under a short timetable. Their strongest argument is that military pressure created leverage, but only diplomacy can restore shipping and monitoring without deepening the economic shock.
- Iranian negotiating side
Iranian officials present Hormuz as a sovereign issue and sanctions relief as the price of de-escalation. Their strongest argument is that Tehran should not give up nuclear or maritime leverage before receiving tangible economic benefit and security guarantees.
- Nonproliferation and security analysts
The Institute for the Study of War warns that ambiguous language and early economic relief could leave Iran better positioned strategically. The strongest version of this view is that a pause in fighting is useful only if it clearly limits missiles, proxies and nuclear breakout pathways.
