Netanyahu Calls on Israel to Overthrow Iranian Regime

The brief

In practical political terms, overthrowing a regime means ending the authority of a country’s existing leadership and replacing it with different rulers or a different political order. It is more sweeping than changing a policy or negotiating a nuclear agreement. Netanyahu argues that Iran’s current leadership itself creates a permanent danger to Israel. His statement came at an Israeli military graduation ceremony, where he told officers there was only one way to remove the threat “once and for all.” The article links that threat to Iran’s repeated “death to Israel” refrain and its nuclear advances, which Tehran says are civilian. It does not describe a specific method for removing Iran’s government. The idea therefore signals an expansive objective rather than a limited military mission. It could shape planning, public messaging, and diplomacy, while increasing the stakes of any renewed strikes. Iran has warned that attacks would trigger retaliation across the Persian Gulf, making regime-change rhetoric especially consequential.

What does “overthrow the Iranian regime” mean in practical political terms?

In practical political terms, overthrowing a regime means ending the authority of a country’s existing leadership and replacing it with different rulers or a different political order. It is more sweeping than changing a policy or negotiating a nuclear agreement. Netanyahu argues that Iran’s current leadership itself creates a permanent danger to Israel.

The idea therefore signals an expansive objective rather than a limited military mission. It could shape planning, public messaging, and diplomacy, while increasing the stakes of any renewed strikes. Iran has warned that attacks would trigger retaliation across the Persian Gulf, making regime-change rhetoric especially consequential.

02

Who are the main actors in this confrontation, and what does each side say it is trying to prevent or achieve?

The main actors are Israel, Iran, and the United States. Benjamin Netanyahu is urging Israel’s military and security agencies to confront Iran’s leadership. Donald Trump has also called Iran an “Evil Regime” and said it must never obtain a nuclear weapon. Their stated concern is that Iran’s leadership and nuclear advances threaten Israel and wider security.

Iran rejects the claim that its nuclear program is for weapons, insisting its advances are civilian. Iranian officials describe renewed fighting as an existential threat to Iran itself. Mehdi Mohammadi warned that a third war in two years could threaten the country’s existence. Mohsen Rezaei threatened retaliation against infrastructure across the Persian Gulf.

Israel and the United States have increased joint training, and officials expect joint strikes to resume after the U.S. midterm elections. Iran says its strategy has “zero red lines.” The confrontation therefore combines competing security claims, nuclear fears, military preparation, and threats of regional retaliation.

03

How large is the potential conflict, given that Iran has threatened attacks across as many as seven Persian Gulf countries and against oil facilities, undersea cables, and data centers?

The threatened scale is regional and could affect systems used by countries far beyond the battlefield. Iran’s security council secretary said fresh U.S.-Israeli attacks would bring strikes against oil facilities, undersea cables, data centers, and artificial intelligence facilities in as many as seven Persian Gulf countries.

Those targets span energy, communications, data storage, and advanced technology. Oil facilities could disrupt fuel production or exports. Damage to undersea cables could interrupt international communications. Attacks on data centers and artificial intelligence facilities could affect digital services and business operations. The article presents these as Iranian threats, not confirmed events.

The conflict could therefore involve several Gulf states even if Israel and the United States are the initial attackers. The scale would depend on whether strikes resume, how Iran responds, and whether threats become action. The possibility of attacks on shared infrastructure makes escalation a concern for regional governments and the wider global economy.

04

What could happen to Israel, Iran, the Persian Gulf region, and the wider world if U.S.-Israeli strikes on Iran resume?

If U.S.-Israeli strikes resume, Israel and Iran could enter another round of direct fighting. Israel might seek to damage Iran’s nuclear capabilities or reduce the security threat Netanyahu describes. Iran has warned that it would respond, turning a bilateral confrontation into a broader regional crisis. The article does not establish how many casualties or how much destruction would result.

Iran’s stated retaliation targets include oil facilities, undersea cables, data centers, and artificial intelligence facilities in as many as seven Persian Gulf countries. Such attacks could threaten energy supplies, communications, financial activity, and digital services. Iran’s officials have also described the next conflict as a threat to their country’s existence.

For Israel and Iran, the danger would be continued war and escalation. For Gulf states, it would mean exposure to attacks despite not being the principal combatants. For the wider world, disruption to energy and communications could spread economic uncertainty. These outcomes remain possibilities, not reported results.

05

Why is Netanyahu emphasizing Iran’s nuclear program and security threat just before Israel’s parliamentary election?

Netanyahu is focusing on Iran because Israel’s parliamentary election is a crucial test of his leadership. His Likud party faces the vote on Oct. 27, and he wants voters to see his government as necessary for national security. Presenting Iran as an existential danger can shift attention toward external threats and his record as a security-focused leader.

The article says this is a tried-and-true political playbook. Netanyahu has long cited Iran’s “death to Israel” refrain and its suspected nuclear ambitions. Iran says its nuclear advances are civilian, but that has not eased Israel’s fears. Israeli forces have also increased training with the United States, reinforcing the message.

The election is the first since Hamas’s Oct. 7, 2023, attack. Analysts view it as a judgment on Netanyahu’s handling of that attack, the resulting conflicts, and his confrontations with major institutions. Emphasizing Iran offers him a way to argue that Likud should remain in office.

06

How did the 2023 Hamas attack and the wars that followed shape the political test Netanyahu now faces?

The 2023 Hamas attack changed the political context of Israel’s election. The article calls it the deadliest attack on Israeli soil since Israel’s founding. It led to devastating conflicts in Gaza, Lebanon, and Iran, placing Netanyahu’s decisions at the center of national debate and international scrutiny.

Analysts see the election as a litmus test of his leadership. They are assessing how he handled the attack and its aftermath, as well as his headstrong approach to institutions such as the United Nations. Rights activists have accused Israeli forces of war crimes against humanity, and genocide, adding intense condemnation to the political pressure.

Netanyahu is responding by emphasizing Iran’s continued threat and presenting security as the election’s central issue. The vote will show whether that message outweighs criticism of his wartime leadership. It also comes as Israel prepares for possible renewed joint strikes, tying the election directly to another potential escalation.

07

Why can a country’s suspected nuclear capability be treated as an existential threat, and what tools besides regime change can states use to address that threat?

A suspected nuclear capability may be called existential when leaders believe it could threaten a country’s survival, not merely cause limited damage. Nuclear weapons can produce catastrophic destruction, so uncertainty about another state’s intentions can intensify fear. In this article, Netanyahu says Iran’s leadership and nuclear ambitions create an existential threat to Israel, while Iran denies pursuing weapons.

The article shows two proposed responses: military strikes and regime change. Israel and the United States are preparing for possible joint strikes, while Netanyahu says removing Iran’s current regime is the only lasting answer. Iran’s officials warn that attacks would threaten Iran’s existence and provoke retaliation. These positions show how each side frames the other as dangerous.

Other tools include negotiations, inspections, sanctions, deterrence, defensive systems, and confidence-building measures. These options are established international policy tools, but the article does not discuss them. Their purpose would be to limit nuclear development, verify claims, deter attacks, or reduce escalation without seeking to remove a government.
