Israel Vows Escalation as Trump Halts Iranian Energy Strikes

On March 27, 2026, Israeli Defense Minister Israel Katz declared that strikes on Iran "will escalate and expand to additional targets and areas that assist the regime in building and operating weapons against Israeli citizens" [1]. Hours earlier, President Donald Trump had extended a pause on US strikes against Iranian energy infrastructure to April 6, citing ongoing negotiations he described as going "very well" [2]. The two announcements laid bare a widening rift between Washington and Jerusalem over how—and whether—to end a war now entering its second month.

The conflict, which began with coordinated US-Israeli strikes on February 28, has killed more than 3,100 people in Iran [3], shut down the Strait of Hormuz to most commercial shipping [4], and sent global oil prices above $118 per barrel [5]. It has also produced no clear path to a ceasefire, with Iran rejecting a US 15-point peace proposal as "maximalist" and "unreasonable" [6] while Israel signals it wants to keep fighting.

Origins: From the Twelve-Day War to Full-Scale Operations

The current conflict did not emerge from a vacuum. In June 2025, Israel launched strikes on Iranian nuclear and military facilities in what became known as the Twelve-Day War. Iran reported 610 citizens killed; Israel reported 28 deaths on its side [7]. A ceasefire followed, but the underlying tensions—Iran's nuclear ambitions, its support for proxy forces, and Israel's determination to prevent a nuclear-armed Iran—remained unresolved.

By late February 2026, US-Iran negotiations had broken down. On February 28, the United States and Israel launched coordinated military operations against Iran. The surprise attack killed Supreme Leader Ali Khamenei along with other senior Iranian officials [7]. Subsequent operations targeted military bases, missile production facilities, air defense networks, government buildings, and—controversially—civilian infrastructure including schools and hospitals [3].

Iran retaliated with missile and drone barrages against Israeli territory, killing at least 19 people in Israel and wounding more than 5,400 [7]. It also closed the Strait of Hormuz to commercial shipping, triggering the largest disruption to global energy supplies since the 1970s [4].

The Strike Campaign: Scale and Targets

The military campaign against Iran has been extensive. The NGO HRANA documented 3,114 deaths in Iran by March 17, including 1,354 civilians, 1,138 military personnel, and 622 unclassified [3]. The Iranian Red Crescent has reported more than 1,900 killed and 20,000 injured [1].

Israel and the US have struck across a broad target set. On March 27, the Israeli military announced it had hit Iran's primary facility for missile and sea mine production in Yazd [1]. The IDF has stated it still has "thousands of targets" remaining and plans at least three more weeks of operations to "systematically degrade Iran's defense industry" [8].

The campaign has achieved significant military results. According to Israeli and US military assessments, more than 100 Iranian air defense systems and approximately 120 detection systems have been destroyed, degrading Iran's air defenses by roughly 80% [9]. Around 70% of Iran's estimated 500 ballistic missile launchers have been destroyed or disabled [10]. Iran's missile launch rate has collapsed by 92% from its day-one peak of 480 launches on February 28 to approximately 40 by March 9 [10].

Trump's Pause: Energy Strikes as Bargaining Chip

President Trump's decision to halt strikes on Iranian energy infrastructure represents a calculated gamble. The initial pause, announced March 23, gave Iran five days [11]. On March 26, Trump extended it to April 6, writing on Truth Social: "As per Iranian Government request, please let this statement serve to represent that I am pausing the period of Energy Plant destruction by 10 Days" [2].

The pause is tied to a broader diplomatic effort. US envoy Steve Witkoff and Jared Kushner have crafted a 15-point peace proposal offering sanctions relief in exchange for the removal of Iran's enriched uranium and other demands [12]. The proposal includes a one-month ceasefire while both sides negotiate the details [12].

Iran has rejected the plan. Tehran has offered its own five conditions: a halt to US and Israeli "aggression and assassinations"; mechanisms to prevent the war from resuming; payment of war reparations; an end to attacks on Hezbollah and pro-Iranian militias in Iraq and Lebanon; and international guarantees for Iran's authority over the Strait of Hormuz [6]. Senior Iranian officials have denied that direct or indirect talks with Washington are taking place [13].

The US-Israel Divergence

The pause on energy strikes has exposed a fundamental disagreement between Washington and Jerusalem over war aims.

According to analysis by the Carnegie Endowment for International Peace, Trump is pursuing a "Venezuela model"—decapitating top leadership while preserving regime structures, then aligning with pragmatic insiders to access resources and reach a deal [14]. Netanyahu, by contrast, favors what analysts describe as a "mowing the grass" strategy: continuous military degradation to weaken Iran durably rather than achieve a negotiated settlement [14].

This divergence manifests in concrete operational tensions. On March 18, the US authorized strikes on Iran's South Pars natural gas field, contradicting earlier restraint on energy targets. Netanyahu subsequently claimed Israel "acted alone" and would refrain from further such attacks—a statement suggesting coordination difficulties [14].

The Foundation for Defense of Democracies noted that while both countries share overlapping objectives, "there is some divergence, and probably an increasing divergence of those objectives as time passes" [15]. A War on the Rocks analysis described the current arrangement as a "blank check" for Israel, with the US providing military cooperation—coordinated planning, intelligence sharing, and joint combat operations—while struggling to constrain Israeli target selection [16].

Russia and China have reportedly provided Iran with satellite imagery and signals intelligence to help compensate for its degraded surveillance capabilities, adding another layer of complexity to the battlefield [17].

Iran's Remaining Military Capabilities

Despite severe degradation, Iran retains meaningful retaliatory capacity. Tehran entered 2026 with an estimated 2,500 ballistic missiles across more than 20 types [9]. Even with 70% of launchers destroyed, the remaining inventory includes medium-range Sejjil and Khorramshahr missiles capable of reaching targets 2,000 to 3,000 kilometers away, as well as the Fattah-2, which Iran claims is a hypersonic glide vehicle traveling at Mach 15 [9].

Iran's most consequential retaliation has been non-kinetic: the closure of the Strait of Hormuz. IRGC commanders have declared that "not a litre of oil" will pass through the strait [4]. Tanker traffic has plunged by more than 90%, and Gulf oil exports have fallen by roughly 60%, with at least 21 confirmed strikes on merchant ships [4]. Major shipping firms Maersk and Hapag-Lloyd have suspended Middle East routes [4].

Iran also retains proxy forces across the region, though the extent to which Hezbollah, Iraqi militias, and Houthi forces can or will act independently of direct Iranian command—given the killing of senior IRGC commanders—remains uncertain.

Economic Fallout: Oil, Inflation, and Global Markets

The war's economic impact has been immediate and severe. Brent crude surpassed $100 per barrel on March 8 for the first time in four years, peaking at $126 per barrel [5]. WTI crude rose from approximately $67 before the conflict to nearly $99 by mid-March [5].

The Strait of Hormuz closure has disrupted approximately 20% of the world's daily oil supply and significant volumes of liquefied natural gas [4]. The Dallas Federal Reserve estimated that the closure could lower global real GDP growth by an annualized 2.9 percentage points in the second quarter of 2026 [18]. Analysts projected that sustained disruption could push oil to $200 per barrel [4].

Before the war, China purchased around 90% of Iran's shipped oil—an average of approximately 1.38 million barrels per day in the first half of 2025 [19]. India relied on the broader region for nearly 60% of its petroleum imports [19]. China, India, Japan, and South Korea collectively account for 75% of oil and 59% of LNG exports transiting the strait [4].

BloombergNEF projected oil could reach $91 per barrel in late 2026 even under a partial-disruption scenario [20]. Beyond oil, price increases have hit aluminum, fertilizer, and helium markets [4]. US stocks have tumbled, with markets reaching new lows as the extended pause on energy strikes failed to reassure investors [21].

The Legal Question: Self-Defense or Aggression?

The legal basis for the US-Israeli military campaign is sharply contested.

International law permits the use of force in only two circumstances: authorization by the UN Security Council, or self-defense against an armed attack under Article 51 of the UN Charter. The Trump administration sought neither [22].

UN special rapporteur Ben Saul stated plainly: "This is not lawful self-defence against an armed attack by Iran, and the UN Security Council has not authorised it" [22]. Rebecca Ingber, a law professor at Cardozo School of Law, noted that the administration's legal rationale remains unclear [22]. Yusra Suedi, assistant professor of international law at the University of Manchester, characterized the strikes as "pre-emptive rather than defensive," noting that Trump himself had previously claimed the June 2025 attacks "obliterated" Iran's nuclear program—undermining claims of imminence [22].

Brian Finucane of the International Crisis Group dismissed the administration's justifications as "scattershot," stating that none of the cited rationales—counterterrorism, regime change, humanitarian intervention—constitute "a serious international legal argument" [22].

Defenders of the operation point to three independent justifications, according to a Duke University Lawfire analysis: collective self-defense on behalf of Israel (given Iranian missile attacks), enforcement of freedom of navigation in the Strait of Hormuz, and the broader right to respond to Iranian-sponsored terrorism [23]. The legal debate remains unresolved, with significant implications for the precedent being set.

The civilian toll has intensified scrutiny. A strike on a girls' elementary school in Minab killed at least 165 people [22]. FIDH (International Federation for Human Rights) has called for the protection of civilians and respect for international humanitarian law [24]. UN experts have called for "de-escalation and accountability" [25].

Gulf States: Reluctant Participants, Shifting Calculus

The Gulf states did not want this war. But Iran's retaliatory strikes—including attacks on Gulf infrastructure—have shifted their calculus.

Saudi Arabia and the UAE have expanded US access to military bases and cooperated on targeting Iranian financial networks, though they have stopped short of direct military engagement [26]. The UAE has taken the hardest line, with officials signaling that the military campaign should continue [27]. Saudi Arabia, by contrast, has used its diplomatic backchannel to Iran "with increased urgency to ease tensions" [28].

Oman has been the clearest voice for restraint. Foreign Minister Badr Albusaidi stated that "the national interests of both Iran and America lie in the earliest possible end to hostilities" [27]. Egyptian officials have reported efforts to build a framework for a 30- to 60-day ceasefire to prevent Saudi Arabia and the UAE from directly responding to Iranian attacks on their territory [28].

The Gulf Cooperation Council states face a difficult position: their economic exposure to a prolonged Hormuz closure is enormous, but so is the perceived opportunity to permanently weaken a regional rival. The IISS (International Institute for Strategic Studies) has assessed that the Gulf states would only enter the war directly if Iran attacks "vital Gulf power and water infrastructure"—a threshold Iran has approached but not clearly crossed [29].

What Comes Next

The April 6 deadline for Trump's energy strike pause now serves as the conflict's next inflection point. If Iran does not agree to terms—and its public statements suggest it will not—the US faces a choice between resuming strikes on energy infrastructure, which would further spike oil prices, or continuing the pause, which would undermine the credibility of its threats.

Israel, for its part, has made clear it does not intend to wait. Katz's pledge to "escalate and expand" suggests broader target sets and deeper penetration into Iranian territory [1]. The IDF's stated plan for three more weeks of systematic operations against Iran's defense industry [8] indicates a timeline that extends well past April 6, regardless of what Washington decides.

Witkoff has expressed confidence that Iran will ultimately accept the 15-point plan, citing "compelling military successes" [12]. But Iran's counter-demands—particularly reparations and international guarantees over the Strait of Hormuz—suggest the two sides remain far apart.

The war has already produced one of the most significant disruptions to the global energy market in decades, killed thousands of people, and tested the limits of international law. Whether it ends with a negotiated settlement or further escalation may depend on decisions made in the next ten days.
