Pakistan Extends Nuclear Umbrella to Saudi Arabia:

A Dangerous New Chapter in Middle East Nuclear Proliferation

Historic defense pact signals shift in regional power dynamics as concerns mount over accelerating nuclear arms race

By Claude AI Anthropic | September 19, 2025

Bottom Line: Pakistan's explicit offer of nuclear protection to Saudi Arabia through a new defense pact marks the first time a nuclear-armed nation has formally placed an Arab Gulf state under its atomic umbrella, potentially accelerating nuclear proliferation across the volatile Middle East.

Historic Nuclear Arrangement

Pakistan's defense minister says his nation's nuclear program "will be made available" to Saudi Arabia if needed under the countries' new defense pact, marking the first specific acknowledgment that Islamabad had put the kingdom under its nuclear umbrella. The Strategic Mutual Defense Agreement, signed Wednesday between Pakistani Prime Minister Shehbaz Sharif and Saudi Crown Prince Mohammed bin Salman, declares that "any aggression against either country shall be considered an aggression against both".

This is Pakistan's most significant formal defense pact in decades, and the first such agreement that an Arab Gulf state has inked with a nuclear-armed partner. The timing appears deliberate—coming just one week after Israel's unprecedented attack on Qatar that killed five Hamas leaders and sparked regional alarm about escalating Israeli military actions.

Speaking to Pakistani television, Defense Minister Khawaja Mohammad Asif emphasized the agreement's nuclear dimension: "What we have, our capabilities, will absolutely be available under this pact".

Regional Security Crisis Driving the Pact

The arrangement emerges from a broader crisis of confidence in US security guarantees following the Trump administration's military actions against Iran in June 2025. On June 22, the United States struck three Iranian nuclear facilities with bunker-buster bombs in what Trump called Operation Midnight Hammer, claiming to have "completely and totally obliterated" Iran's nuclear enrichment capabilities.

However, the strikes appear to have accelerated, rather than prevented, regional nuclear proliferation. An early US intelligence assessment suggests the strikes "did not destroy the core components" of Iran's nuclear program and "likely only set it back by months," contradicting Trump's public claims.

More significantly, the attacks demonstrated to Gulf allies that US military action could provoke dangerous retaliation without providing lasting protection. Iran launched missiles against a US military base in Qatar in response to the American strikes, marking "the first-ever direct Iranian strike on a Gulf state". Qatar's hosting of the Al Udeid Air Base, largest US military base in the Middle East, "proved ineffective in deterring an Israeli strike aimed at Hamas in Qatar, suggesting that for all its strategic weight, the US military footprint in the Gulf may no longer serve as the shield it was once thought to be".

Long-Standing Nuclear Partnership

The current arrangement builds on decades of cooperation. It is widely believed that Saudi Arabia has been a major financier of Pakistan's own integrated atomic bomb project since 1974, a program founded by former prime minister Zulfikar Ali Bhutto. After Pakistan's first nuclear test in 1998 landed it under international sanctions and diplomatic isolation, Saudi Arabia provided crucial support. The very next day, Pakistan was promised $3.4 billion in Saudi financial support, funds that helped Islamabad proceed with a second nuclear test.

Perhaps most revealing was a 2024 conversation reported by journalist Bob Woodward, where Saudi Crown Prince Mohammed told US Senator Lindsey Graham that Riyadh planned to enrich uranium only for energy purposes. When Graham expressed concern about the prospect of a Saudi bomb, Crown Prince Mohammed replied: "I don't need uranium to make a bomb. I will just buy one from Pakistan".

Nuclear Capabilities and Strategic Reach

Pakistan possesses approximately 170 nuclear warheads, while India has an estimated 172, according to the U.S.-published Bulletin of Atomic Scientists. Critically, Pakistan's Shaheen 3 ballistic missile, believed to be able to carry both conventional and nuclear warheads, has a maximum range of 2,750 kilometers (1,700 miles) — making it capable of reaching Israel.

The Trump administration has imposed sanctions targeting Pakistani individuals and firms over alleged ballistic missile development, and administration officials have publicly raised concerns over the range of missiles Pakistan is building, and whether they could carry nuclear weapons as far as the US.

Iran's Nuclear Crisis Accelerating Proliferation

The Pakistan-Saudi arrangement comes as Iran's nuclear program faces unprecedented pressure. The UN nuclear watchdog's board of governors formally found that Iran was not complying with its nuclear obligations, with 19 countries voting for the resolution. Iran responded by announcing plans to establish a new enrichment facility "in a secure location".

Analysts and researchers say that a nuclear-armed Iran poses significant global security risks and undermines the stability of the Middle East. International Atomic Energy Agency (IAEA) chief Rafael Grossi warns that an Iranian nuclear weapon could trigger broad nuclear proliferation, as other countries, particularly in the Middle East, may seek similar capabilities in response.

According to Carnegie Endowment analysis, "A single cascade of 174 IR-6 centrifuges could produce a bomb's worth of 90% highly enriched uranium from the 60% enriched material, whose location is unknown, in 10-20 days".

Signal to Israel

The pact is widely viewed as a strategic message to Israel, long believed to be the Middle East's only nuclear-armed nation. On 13 June 2025, Israel launched a series of attacks against Iran's nuclear facilities, its nuclear scientists, and senior commanders in the Islamic Revolutionary Guard Corps, followed by American bomber jets supporting the assault, dropping massive bunker-buster bombs on Fordow, one of Iran's key nuclear sites.

"These events have exacerbated security anxieties of the Gulf states while jeopardising confidence in the US security umbrella as the ultimate shield. As Gulf states look to bolster their security, regional countries such as Pakistan, Egypt and Turkiye emerge as natural partners", said analyst Cinzia Bianco.

International Response and Concerns

India's Foreign Ministry acknowledged the Saudi-Pakistan pact and said it "will study the implications of this development for our national security as well as for regional and global stability"—a significant statement given that India and Pakistan fought a brief military conflict in May 2025.

"Pakistan already has a credibility problem in Washington, and this agreement won't reduce it," security analyst Sahar Khan told Al Jazeera.

US Position: Caught Between Allies

The Pakistan-Saudi nuclear arrangement places the United States in an extraordinarily difficult position, caught between two key allies while facing the erosion of its role as the region's primary security guarantor. Gulf Arab states grow increasingly wary about the reliability of the United States as their longstanding security guarantor.

The Trump administration's handling of the Iranian crisis has further damaged US credibility. Trump initially sought nuclear negotiations with Iran, telling allies he was "getting very close" to a nuclear deal and instructing Netanyahu to hold off on strikes to give diplomacy more time. When Israel proceeded with attacks anyway, Trump was forced to choose between appearing weak or joining the military campaign—ultimately launching the largest B-2 bomber strike in US history without congressional approval.

Limited US Leverage

Washington's ability to influence this arrangement is constrained by historical precedent and current realities. Building an enrichment facility in the kingdom would be seen as a major reversal of U.S. nonproliferation policy, yet blocking Saudi nuclear ambitions entirely may be unrealistic given alternative partnerships with China and Russia.

Congressional leaders have called on the administration to condition any U.S.-Saudi civil nuclear deal on a binding commitment from the kingdom to forswear enrichment and reprocessing capabilities. However, Saudi Arabia has been developing its own nuclear capabilities, announcing in January 2025 plans to enrich and sell uranium as part of its civilian nuclear program.

The Trump administration has responded positively to Saudi Arabia's interest in civil nuclear cooperation with the United States, with officials saying they are "very excited" at the prospect. U.S.-Saudi cooperation in building reactors for nuclear power plants in the kingdom could shut the Chinese and Russians out of what could be a high-dollar partnership for the American nuclear industry.

Broader Proliferation Threat

The security architecture dissuading countries from growing and pursuing their own nuclear weapons is collapsing, warned analysts in The Washington Post. In the face of new uncertainties, even U.S. allies — from South Korea to Saudi Arabia to Germany — are reckoning with the merits of boosting their nuclear programs.

Iranian officials maintain that their new law does not violate these obligations, that it merely suspends (rather than terminates) its required IAEA safeguards agreement. But this measure could very well be a prelude to an even bigger escalation: Iran's withdrawal from the Nuclear Non-Proliferation Treaty (NPT).

What's Next

The door remains open for other nations to join similar arrangements. Pakistani Deputy Prime Minister Ishaq Dar noted that "after this development, other countries have also expressed a desire for similar arrangements".

While some analysts argue the pact is more symbolic than substantive, its implications for regional stability are significant. Defense cooperation ≠ automatic war pledge, and signaling ≠ nuclear guarantee, notes Harvard's Belfer Center, yet the arrangement fundamentally alters Middle Eastern security calculations.

As nuclear tensions escalate across the Middle East, the Pakistan-Saudi defense pact represents a watershed moment that could reshape regional security architecture for decades to come. Whether it serves as a deterrent to further conflict or accelerates a dangerous nuclear arms race will likely depend on how other regional powers—particularly Israel and Iran—and crucially, the United States, respond to this new strategic reality.
