Israeli Defense Minister Warns Strikes on Iran Could Resume Soon, Says Campaign Is Not Over

Israeli Defense Minister Israel Katz told an audience of military commanders on April 30, 2026, that Iran had suffered "extremely severe blows over the past year, blows that set it back years in every field" — but added that Israel may soon "be required to act again to ensure the achievement of those goals" [1]. The remarks, made at a ceremony promoting the incoming Israeli Air Force commander, amounted to the most direct public signal from a senior Israeli official that the fragile ceasefire with Iran could collapse.

The timing was not subtle. On the same day, Israel's Defense Ministry announced two cargo ships had docked at Ashdod and Haifa and multiple transport aircraft had arrived within 24 hours, delivering roughly 6,500 tons of military equipment — munitions, trucks, and combat vehicles [1]. Since Operation Roaring Lion began, Israel has received more than 115,600 tons of military equipment through 403 flights and 10 maritime shipments [1].

A Year of Escalation: October 2024 to April 2026

The trajectory from limited exchanges to full-scale war was steep.

In October 2024, Israel launched Operation Days of Repentance — three waves of strikes hitting 20 locations across Iran, Iraq, and Syria, the largest foreign attack on Iran since the Iran–Iraq War [2]. Over 100 aircraft, including F-35 stealth fighters, flew 2,000 kilometers to destroy what U.S. and Israeli officials said was the majority of Iran's S-300 air defense network and significant missile production infrastructure [2][3]. Iran reported four soldiers and one civilian killed and insisted the damage was "limited" [2].

In June 2025, Israel launched the Twelve-Day War — surprise strikes against Iranian military and nuclear facilities that dramatically escalated the conflict [4]. By the end of the 12 days, the independent monitoring group Human Rights Activists in Iran (HRANA) reported 1,190 deaths: 435 military personnel, 436 civilians, and 319 whose status could not be confirmed [5]. Israeli strikes during this period killed 28 Israeli civilians and one off-duty soldier from Iranian retaliatory fire, with 3,238 hospitalized injuries in Israel [5].

On February 28, 2026, the United States and Israel jointly launched a new wave of strikes on Iran targeting military installations, government sites, and several senior officials — including Supreme Leader Ali Khamenei [4][6]. Iran retaliated, and the fighting continued through a conditional ceasefire declared on April 8, mediated by Pakistan [7].

The Ceasefire: Fragile by Design

The April ceasefire required Iran to reopen the Strait of Hormuz in exchange for a halt in strikes. By April 9, ships were again being prevented from transiting the strait, and both sides accused the other of violations [8]. On April 21, President Trump extended the ceasefire while keeping the naval blockade in place and instructing the U.S. military to remain prepared to resume fighting [8].

Defense Minister Katz's April 30 statement landed squarely in this ambiguous space — a ceasefire that neither side treats as permanent.

Maj. Gen. (ret.) Yaakov Amidror, a former Israeli national security adviser, told Fox News Digital that Washington and Jerusalem are preparing for two paths: a prolonged blockade to economically exhaust Iran, or renewed military action [1]. "When leadership decides they are sufficiently prepared," Amidror said, the decision could come quickly [1].

Iran's Nuclear Program: The Central Question

The stated justification for Israeli strikes has consistently been Iran's nuclear program. The evidence on whether the strikes achieved their objectives is contested.

As of September 2025, the IAEA reported that Iran possessed 440.9 kilograms of uranium enriched to 60% U-235 — enough, if further enriched to weapons-grade (90%), for approximately nine nuclear weapons [9]. A single cascade of 175 IR-6 centrifuges could produce enough weapons-grade material for one bomb every 25 days [9].

IAEA Director General Rafael Grossi told the Associated Press on April 29, 2026, that roughly 200 kilograms of this material — stored in blue containers — entered a tunnel complex at the Isfahan nuclear site on June 9, 2025, just before the Twelve-Day War began, and is likely still there [10][11]. "We haven't been able to inspect or to reject that the material is there and that the seals — the IAEA seals — remain there," Grossi said [10].

IAEA inspectors have not accessed Isfahan since June 2025 [10]. The agency also reported it has not inspected a newly declared underground enrichment facility at Isfahan and does not know whether centrifuges have been installed [12]. After the June strikes, Iran began accelerating construction on an underground site at Kūh-e Kolang Gaz Lā, tunneled into the Zagros mountain range roughly a mile south of the Natanz facility, and announced plans to install advanced centrifuges at a new enrichment site [13].

This is the core of the counterproductive-strikes argument: the war energized those in Tehran who have long argued that Iran should enrich uranium to weapons-grade and fast-track bomb production [13]. Whether it also changed the calculus of more cautious actors — including the late Supreme Leader Khamenei — remains unclear [13].

The Humanitarian Toll

As of April 7, 2026, HRANA documented 3,636 deaths in Iran from Israeli and U.S. strikes during the 2026 war alone: 1,701 civilians, 1,221 military personnel, and 714 unclassified [5][14]. The broader regional toll included an estimated 2,509 dead in Lebanon and 28 killed in Gulf states [5].

The Red Crescent reported that by March 7, 2026, over 6,668 civilian units had been targeted, including 5,535 residential units, 1,041 commercial units, 14 medical centers, 65 schools, and 13 Red Crescent–affiliated centers [14]. HRANA estimated that at least 15% of total casualties were under 18 [14]. Some 307 health and medical facilities in Iran had been damaged as of April 3 [14].

The UNHCR estimated total displacement in the region at 4.8 million people. Roughly one million households in Iran fled their homes; 1.05 million people — 20% of the population — were internally displaced in Lebanon [14]. Relief operations in the region were only 19% funded against a $454 million requirement, with Iran at just 11% funded against $140 million [14].

Official Iranian and Israeli government statements have consistently understated these figures. Iran initially described damage from the October 2024 strikes as "limited" [2]. Israeli officials have emphasized the precision of targeting military infrastructure.

Iran's Retaliatory Capacity: Diminished but Not Eliminated

Iran's ability to strike back has declined, but it retains meaningful firepower.

Before the June 2025 war, Iran was estimated to hold around 2,500 ballistic missiles — the largest such arsenal in the Middle East [15]. After firing roughly 550 missiles during the Twelve-Day War and losing between a third and half of remaining stockpiles to Israeli strikes, estimates of Iran's current inventory range from 1,000 to 1,200 missiles, with only about 100 serviceable mobile launchers remaining from an original pool of 480 [15][16].

Between February 28 and April 20, 2026, Iran launched 1,471 ballistic missiles toward Israel, Jordan, Qatar, Kuwait, Bahrain, Saudi Arabia, the UAE, Oman, and Turkey [15] — a rate that analysts at the Jewish Institute for National Security of America (JINSA) warned risks exhausting remaining launch capacity under continued counterstrikes [16].

Iran's industrial base can produce several hundred missiles per month, and underground "missile cities" built over decades provide some production resilience [15]. But current output is constrained by damage to production facilities and supply chain disruptions.

Iran's proxy network — once its primary asymmetric tool — has been severely degraded. Israel's campaign in Lebanon dismantled Hezbollah's senior leadership, including longtime chief Hassan Nasrallah, and destroyed much of its military infrastructure [17]. Iraqi militias, under pressure from U.S. strikes and sanctions, face internal political fractures, and most Popular Mobilization Forces stayed out of the 2026 conflict [17]. The Houthis in Yemen retain the capacity for Red Sea shipping attacks but have become more operationally independent from Tehran [17].

Russia, China, and the Widening Strategic Picture

The conflict has accelerated Iran's integration with Russia and China. In January 2026, the three countries signed a trilateral strategic pact described by their state media as "a cornerstone for a new multipolar order" [18]. Iran's foreign minister confirmed in March 2026 that Tehran was receiving "military cooperation" from both Moscow and Beijing [19].

Russia has reportedly provided Iran with satellite imagery and damage assessments to improve Iranian targeting [19][20]. China has supplied dual-use components including rocket fuel ingredients and satellite data [20]. Russia's Alabuga facility in Tatarstan includes a drone assembly plant linked to Iranian weapons programs [20].

This is the second prong of the counterproductive-strikes argument: each round of Israeli strikes has driven Iran deeper into partnership with two nuclear-armed powers whose interests do not align with Washington's. Whether this cooperation rises to the level of a formal military alliance or remains transactional is debated by analysts [21].

Inside Israel: Who Wants to Resume, and Why Now?

Leaked transcripts from security cabinet meetings, published by the Times of Israel, reveal that Netanyahu told ministers at the start of the June 2025 war that the "main thing" was striking the underground Fordo enrichment facility and "creating a huge balance of terror" with Iran [22]. The transcripts also showed Israeli leaders discussed seeking an opportunity to assassinate Khamenei, destabilize the Tehran regime, and induce residents to flee the capital [22].

Defense Minister Katz has taken a consistently hawkish public line, warning in March 2026 that Israeli attacks on Iran "will escalate and expand" and that "Tehran will burn" if Iran continues retaliatory strikes [23]. His April 30 statement fits this pattern.

Within Israel's political spectrum, public dissent over Iran strikes has been limited. When the February 2026 strikes were launched, politicians from the right to the center-left — including opposition figures Yair Lapid and Naftali Bennett — rallied behind Netanyahu [24]. The domestic political incentive runs in one direction: supporting military action against Iran carries no meaningful political cost in Israel's current environment.

The timing of Katz's public warning — rather than operational silence — is itself telling. Retired Israeli military figures and think-tank analysts have noted that public threats serve a dual function: signaling resolve to Tehran and building domestic and international political cover for a resumption of strikes [1]. The concurrent military resupply announcement reinforces this: it tells Iran, the United States, and the Israeli public that the infrastructure for another round is in place.

The Diplomatic Landscape

International reaction to the 2026 war was sharply divided. Norway's foreign minister said the initial Israeli-U.S. strike "is not in line with international law" [7]. UN Secretary-General Guterres condemned the strikes and said they "squandered an opportunity for diplomacy," noting they came while indirect U.S.-Iran talks mediated by Oman were ongoing [25]. Russia's UN representative compared the justification to false WMD claims about Iraq [7].

The UK, France, and Germany condemned Iran's counter-strikes in a joint statement but called for a resumption of diplomacy, with UK Prime Minister Keir Starmer saying he did "not believe in regime change from the skies" [7][24].

The United States under Trump has taken a different position, maintaining that pressure must continue until a "real deal" addressing Iran's nuclear program is reached [1]. The question of whether Washington would participate in a renewed Israeli strike campaign — or merely provide the 115,600 tons of equipment and political cover — remains unanswered.

What Comes Next

The ceasefire is a pause, not a resolution. Iran's enriched uranium sits in tunnels the IAEA cannot inspect. Israel's military stockpiles are being replenished at industrial scale. Iran's missile inventory is diminished but not exhausted, and its reconstruction is underwritten by Russian and Chinese support.

Katz's warning puts a specific question on the table: does another round of strikes bring Israel closer to the stated goal of neutralizing Iran's nuclear capability, or does it repeat the pattern of the past year — tactical damage followed by strategic acceleration of the very program the strikes aimed to destroy?

The IAEA's Grossi put the verification challenge plainly: without inspectors on the ground, no one outside Tehran knows the answer [10].
