A new nuclear umbrella rises over the Gulf as confidence in the US fades

The Saudi-Pakistan defense pact could give Riyadh a nuclear-backed deterrent as Iran, Israel and US reshape Gulf security calculations The rapidly evolving security landscape in the Middle East is prompting Saudi Arabia to rethink its national defense strategies. With no reliable guarantees of American protection, Riyadh is looking to establish an alternative framework for reliable defense – and surprisingly, Pakistan is becoming its key component. The Saudi-Pakistani Strategic Mutual Defense Agreement (SMDA), signed last September by Crown Prince of Saudi Arabia Mohammed bin Salman and Prime Minister of Pakistan Shehbaz Sharif, is one of the most significant pacts between the two nations in recent decades. Its central provision states that aggression against one state will be automatically regarded as aggression against both, echoing the principles of classic collective security treaties and formally establishing allied relations between the two countries. However, the deliberately vague wording concerning specific response mechanisms allows both parties considerable political maneuverability. In diplomatic agreements this is standard practice. The true value of this agreement, however, lies in the context in which it was concluded and, according to Pakistani sources, its potential. Islamabad possesses an estimated arsenal of 150-160 nuclear warheads and a well-developed nuclear missile delivery system, including short-and medium-range missiles. The agreement legally allows for the consideration of Pakistan’s nuclear capabilities in the defense of Saudi Arabia, effectively creating the first ‘nuclear umbrella’ in the Islamic world, founded not on Western guarantees but on mutual Muslim solidarity reinforced by shared strategic interests. The pragmatic implications of this arrangement are clear. For Riyadh, the primary source of existential anxiety is Shiite Iran, which vies for dominance in the region and is armed with an extensive network of proxy forces throughout the Middle East.

The US serves as a military counterbalance to Tehran; however, the Trump administration has clearly demonstrated the limits of its reliability. Washington’s tacit support for Israeli strikes on Qatar last September revealed its willingness to sacrifice the interests of regional allies for its own agenda, a precedent that did not go unnoticed in Riyadh. Today, amid a direct military conflict between the US and Iran (and despite the fragile ceasefire which may be broken at any moment) the situation has become even more tense. Since February 28, American strikes on Iran have failed to yield substantial results, and if US President Donald Trump is unable to subdue Tehran, Iran may emerge from this crisis significantly strengthened, acquiring the status of an undefeated regional power. This means Riyadh would face a formidable neighbor with a stronger-than-ever geopolitical standing. This scenario compels Saudi Arabia to treat its partnership with Pakistan seriously. While Washington wages war, Riyadh seeks to ensure its own security. Read more This is what superpowers must learn from the US war against Iran Moreover, a different kind of threat is also emerging. Under Prime Minister Benjamin Netanyahu, Israel has consistently resorted to force and has been able to get away with it. The only nation that has confronted Israel is Iran, but the odds are stacked against Tehran; it now faces not just Israel but a full-fledged US-Israeli alliance. Saudi Arabia finds itself in a particularly precarious position, caught between an aggressive Israel and an ambitious Iran; yet unlike Tehran, it lacks both the military capability and the political will for independent resistance. This vulnerability makes partnership with Pakistan less of a diplomatic gesture and more a matter of survival. Achieving strategic parity with such a player through traditional military means is unrealistic
