The Islamic Republic of Iran’s nuclear program have been a centerpiece of Middle Eastern geopolitics for more than two decades, drawing sharp opposition from the United States and Israel. While Iran maintains that its nuclear program is strictly for peaceful purposes—such as energy production and medical research—its adversaries remain deeply skeptical. The core of their opposition lies not only in security threats but also in concerns over regional balance of power, proliferation risks, and ideological hostilities.
Strategic Anxiety: Nuclear Iran as a Regional Power
At the heart of U.S. and Israeli opposition is the belief that a nuclear-armed Iran would dramatically shift the balance of power in the Middle East. The region is already a tinderbox of competing interests and volatile alliances, and both Washington and Tel Aviv argue that Tehran with nuclear capability would embolden its foreign policy, undermine their allies, and potentially spark a nuclear arms race.
Israel, in particular, sees the Iranian regime as an existential threat. Since the 1979 Islamic Revolution, Iran has consistently called for the elimination of the Israeli state. Iran funds and supports anti-Israel militant groups such as Hezbollah in Lebanon and Islamic Jihad in Gaza. In Israeli strategic doctrine, the possibility of such a regime possessing a nuclear weapon—no matter how remote—is simply intolerable.
The United States, while not facing a direct existential threat, sees Iran’s nuclear ambitions as a severe challenge to its long-standing role as the primary security guarantor in the Gulf region. A nuclear Iran could coerce U.S. allies like Saudi Arabia and the United Arab Emirates, complicate U.S. military operations in the region, and reduce U.S. influence overall.

Israel’s “Begin Doctrine” and Preventive Strategy
Israel’s opposition to Iranian nuclearization is not merely rhetorical. The country has a long history of preemptive action against perceived existential threats. In 1981, Israel bombed Iraq’s Osirak nuclear reactor, fearing that Saddam Hussein’s regime was developing a nuclear weapon. In 2007, it carried out a similar airstrike on a suspected Syrian nuclear facility.
This informal policy—known as the Begin Doctrine, named after former Prime Minister Menachem Begin—holds that Israel will not allow any hostile neighboring state to develop nuclear weapons. Iran, from Israel’s point of view, is not just another hostile state; it is the most potent ideological and military adversary in the region, with advanced missile capabilities, a sprawling network of proxy militias, and the explicit aim of dismantling the Jewish state.
Given this context, it’s no surprise that Israel has conducted cyber-espionage campaigns, sabotage missions, and even assassinations of Iranian nuclear scientists, according to multiple international intelligence sources. The infamous Stuxnet virus, a joint U.S.-Israeli cyberweapon deployed around 2010, reportedly destroyed hundreds of centrifuges at Iran’s Natanz facility. These actions underline Israel’s commitment to halting Iran’s nuclear progress by any means necessary.

The U.S. Perspective: Non-Proliferation and Regional Stability
For the United States, the primary concern is nuclear non-proliferation. The U.S. has long championed the Nuclear Non-Proliferation Treaty (NPT) and sees Iran’s potential to develop nuclear weapons as a threat to the global norm against nuclear spread. Washington fears that if Iran gets the bomb, other Middle Eastern powers—especially Saudi Arabia—would feel compelled to pursue nuclear weapons themselves, unraveling decades of non-proliferation efforts.
Moreover, successive U.S. administrations have worried that a nuclear Iran would escalate conflicts across the Middle East. Tehran already supplies weapons and funding to various Shia militias and armed groups in Iraq, Syria, Lebanon, and Yemen. With the deterrent shield of nuclear capability, it could expand its regional footprint with reduced fear of retaliation, potentially provoking wider wars and destabilizing already fragile states.
Ideological Divide and Diplomatic Breakdown
Beyond security and strategy lies a deep ideological divide. The U.S. and Iran have been adversaries since the 1979 U.S. Embassy hostage crisis in Tehran. Iran’s clerical leadership continues to frame the U.S. as the “Great Satan,” and hardline factions routinely reject engagement with the West. This longstanding enmity colors every negotiation and heightens mutual distrust.
This mistrust was partially bridged during the Obama administration, which culminated in the 2015 Joint Comprehensive Plan of Action (JCPOA)—commonly known as the Iran Nuclear Deal. Under the JCPOA, Iran agreed to limit its nuclear enrichment activities, reduce its uranium stockpile, and submit to rigorous international inspections in exchange for sanctions relief.
While hailed by many as a diplomatic triumph, the deal had its detractors—especially in Israel and among U.S. Republicans. Critics argued that the JCPOA allowed Iran to maintain some enrichment capacity and that its sunset clauses meant Iran could legally resume advanced nuclear activities within a decade. They also noted that the deal did not address Iran’s ballistic missile program or its support for terrorism.

Trump’s Withdrawal and Maximum Pressure against Iran’s Nuclear Program
In 2018, President Donald Trump unilaterally withdrew from the JCPOA, calling it a “disaster” and reinstating harsh economic sanctions. This move was cheered by Israel and some Gulf states but criticized by European allies. Iran, in response, gradually breached the deal’s limits—enriching uranium to higher levels, installing advanced centrifuges, and limiting International Atomic Energy Agency (IAEA) inspections.
The Trump administration pursued a “maximum pressure” campaign aimed at crippling Iran’s economy and forcing it back to the negotiating table for a more comprehensive agreement. However, the strategy failed to yield a new deal. Instead, it brought Iran closer to nuclear weapons capability, according to IAEA estimates, while inflaming tensions across the Middle East—from rocket attacks in Iraq to tanker seizures in the Persian Gulf.
The Biden Era: Stalled Diplomacy and Military Options
President Joe Biden came into office vowing to return to the JCPOA if Iran also returned to compliance. Months of indirect negotiations in Vienna produced no breakthrough. By 2023, talks had all but collapsed, and Iran’s nuclear program had advanced far beyond its pre-2015 level.
The Biden administration now faces a difficult choice: risk another major war in the Middle East or tolerate a near-nuclear Iran. Meanwhile, Israel has continued to signal its willingness to act alone if necessary. In 2022 and 2023, Israeli officials made public threats of military strikes and conducted joint air drills with the U.S. military, simulating long-range bombing missions—clear signals to Tehran.

A Ticking Clock: The Risk of Miscalculation
Today, the stakes remain alarmingly high. Iran is estimated to be only weeks away from having enough enriched uranium for a bomb, though weaponization could take longer. The U.S. and Israel maintain that they will not allow this to happen—but it’s unclear what red lines remain, and how they will enforce them.
A preemptive Israeli strike could trigger a massive regional war, dragging in Hezbollah in Lebanon, militias in Iraq, and possibly even direct confrontation with Iran. The U.S., while more cautious, may find itself compelled to support Israel militarily. In such a scenario, the prospects for diplomacy would vanish, and the Middle East could plunge into yet another catastrophic conflict.
The Shadow of the Bomb
The opposition of the United States and Israel to Iran’s nuclear program is not merely about uranium enrichment or technical thresholds. It’s about ideology, deterrence, power projection, and survival. For Israel, it’s an existential matter. For the U.S., it’s a battle to uphold global non-proliferation and maintain regional influence.
Whether through diplomacy, deterrence, or military confrontation, the Iran nuclear question remains a defining challenge of 21st-century international security—and one that could explode into a far wider crisis if not carefully managed.
