Iran and Israel engaged in a renewed exchange of direct military strikes overnight Sunday, shattering a fragile two-month ceasefire championed by President Donald Trump and raising the specter of a full-scale war.
This complex cycle of tit-for-tat aggression—spanning Lebanon and direct clashes between Iran and Israel—presents a significant hurdle for Mr. Trump, who maintained on Sunday that a comprehensive peace agreement remains within reach.
The escalation highlights Tehran’s strategic attempt to reshape regional dynamics. Iran is seeking a broad ceasefire that guarantees the protection of its ally, Hezbollah, and limits Israeli and American military actions, which Tehran views as frequent violations of regional stability.
By Monday afternoon, Iran’s top military command, Khatam al-Anbiya, announced a cessation of operations. However, the command issued a stern warning that any continued Israeli aggression, particularly in southern Lebanon, would provoke a “more severe” response.
Israeli Prime Minister Benjamin Netanyahu stated that he would “hold fire” for the time being, but cautioned that Israel would “respond powerfully” should Iran make a strategic mistake and resume its attacks.
The escalation began late Sunday when Iranians launched a volley of ballistic missiles, sending Israeli civilians rushing to bomb shelters. This attack occurred hours after Israel expanded its military operations in the southern suburbs of Beirut. Iranian officials had previously warned that such actions would trigger a direct response, following weeks of Israeli operations and fighting with Hezbollah in southern Lebanon despite a U.S.-brokered ceasefire.

Israel retaliated with airstrikes targeting Tehran and several other cities, defying President Trump’s request to refrain from a counterattack. The U.S. president had claimed Sunday that he was only days away from negotiating an end to the conflict, which began jointly with Israel on February 28. One of Israel’s primary targets was the petrochemical complex at Mahshahr in southwestern Iran.
The Israel Defense Forces (IDF) justified its strikes on Beirut’s Dahieh suburb as a response to Hezbollah’s attacks on northern Israel. The IDF further stated it would not allow Iran to establish a “new equation” by responding directly to Israeli actions in Lebanon, vowing to intensify operations against Hezbollah.
Analysts suggest that Iran’s direct strikes are intended to formalize the claim that the fate of Hezbollah and the situation in Lebanon are inextricably linked to Iran’s broader conflict with the U.S. and Israel, encompassing issues ranging from its nuclear program to its influence over the Strait of Hormuz.
“Tehran’s decision to answer a strike on Lebanon with missiles launched from its own soil is the operative development here,” noted Hamidreza Azizi, an Iranian security expert at the German Institute for International and Security Affairs, in a post on X.
According to Dr. Azizi, this move gives “concrete form” to Foreign Minister Abbas Araghchi’s position that a ceasefire must apply across all fronts simultaneously. “For weeks, this remained a rhetorical position, but [Sunday] Tehran attached a cost to it,” Azizi wrote. “Iran responded directly, with its own missiles, rather than through Hezbollah… the missile force has become Tehran’s primary tool for direct retaliation and coercive signaling.”

In Israel, where Mr. Netanyahu is facing an October election, the decision to retaliate was particularly notable given Mr. Trump’s public opposition to a counterattack. The Financial Times reported that Mr. Trump asserted, “I call all the shots,” suggesting that Mr. Netanyahu does not. Since last year, Mr. Trump has reportedly urged Netanyahu to curb military operations that might jeopardize truce efforts.
However, Daniel Sobelman, an assistant professor of International Relations at the Hebrew University of Jerusalem, suggests the retaliation was likely coordinated with the U.S. to some degree. “I don’t think that Netanyahu would have just flat-out defied Trump,” he said.

“What Iran is trying to do is safeguard Hezbollah and restrict Israel’s latitude in Lebanon,” Dr. Sobelman explained. He added that it was imperative for any Israeli prime minister to prevent Iran from establishing new “rules of the game” where Israeli actions in Lebanon trigger direct ballistic missile attacks from Iranian soil.
The tension led to the closure of schools in Israel on Monday, and hospitals entered emergency mode, relocating many patients underground as citizens were urged to stay near safe rooms.
In Iran, Mohammad Baqer Qalibaf, the Speaker of Parliament and a key liaison in indirect talks with the U.S., argued that the American naval blockade and the “green light” given to Israel for the Beirut attacks turned U.S. and Israeli assets into “legitimate targets.”
Foad Izadi, a professor at the University of Tehran, told the BBC that Iran is attempting to establish the operational rules for the coming years. “The aim of the strike is to tell the other side that Iranians are not fools,” he said, arguing that Israel’s actions in Beirut were a serious violation of the expected ceasefire.
The current Iranian leadership is dominated by hard-liners following the death of Supreme Leader Ayatollah Ali Khamenei in early Israeli strikes. He was succeeded by his son, Mojtaba Khamenei, who was also reportedly injured in the attack. These hard-liners argue that continued attacks on Israeli and U.S. forces are necessary to reestablish deterrence.
Conversely, many in Israel argue that because regime change in Iran has not occurred and its nuclear and regional networks remain intact, the fighting should continue. Oded Ailam, a former Mossad counterterrorism head, described the April 8 ceasefire as a “major mistake” and viewed the current escalation as an opportunity to “correct” previous strategic errors.
Ailam noted that Israel remains dependent on U.S. coordination through CENTCOM. He suggested that this volatility may actually serve American interests by providing leverage during a diplomatic stalemate, predicting that the U.S. will eventually step in as the “school master” to return both parties to the negotiation table.
