Amid rising tensions along the Pakistan-Afghanistan border, experts say the newly signed Saudi-Pakistani mutual defense pact is largely symbolic and unlikely to alter the regional balance of power.

On Friday, Afghanistan accused Pakistan of carrying out airstrikes on its territory, shattering a temporary ceasefire after days of escalating clashes that marked the deadliest fighting along the border in years.

“The truce has been broken and Afghanistan will retaliate,” a spokesman for the Taliban-led Afghan government said in a statement, announcing that Pakistan had “broken the ceasefire and bombed three locations in Paktika,” a province in the country’s eastern region.

Earlier this week, the two nations had agreed to a 48-hour ceasefire after border clashes killed dozens of troops.

The conflict erupted after Pakistan accused its neighbor of harboring and supporting terrorist groups responsible for attacks on its territory, while Afghanistan accused Pakistan of violating its airspace and carrying out strikes in the country’s eastern regions.

The fragile ceasefire came after appeals from major regional powers, including Saudi Arabia, with which nuclear-armed Pakistan signed a mutual defense pact last month, further solidifying a decades-long security partnership.

According to experts, the recent regional escalation shows how the Saudi-Pakistan partnership is largely symbolic, offering diplomatic backing and condemnation but unlikely to be tested in practice.

“”The recent Pakistan-Afghanistan clashes are unlikely to lead to invocation of the Saudi-Pakistan defense pact,” Edmund Fitton-Brown, a senior fellow at the Foundation for Defense of Democracies (FDD), a Washington, DC-based think tank, told The Algemeiner.

He explained that the threat from Afghanistan, while politically serious, is not strong enough to push Pakistan to seek support from a third party, since the country is far stronger than the hostile forces along the contentious border.

“The Saudis, as central players in the Islamic world, will also want to be seen as welcoming Afghanistan’s gradual rehabilitation,” Brown said, noting that even if the pact were invoked, it is unlikely they would want to intervene in the conflict.

More broadly, he argued that this recent escalation underscores the limits of the Saudi-Pakistan defense pact, emphasizing that “most of the challenges that both countries face do not rise to the level of war between states.”

“”The possible war scenarios that do exist — Pakistan with India, Saudi Arabia with Iran — are not ones in which the other party to the pact would want to get involved, and it is inconceivable that Pakistan is offering a nuclear guarantee to the Saudis,” Brown told The Algemeiner.

Pakistan has repeatedly argued that its nuclear weapons are intended solely as a deterrent against India.

As the only nuclear-armed, Muslim-majority nation with the Islamic world’s largest army, Pakistan’s newly signed defense pact has raised questions about shifts in Middle East power and regional dynamics.

“”The agreement states that any aggression against either country shall be considered an aggression against both,” the Pakistani Prime Minister’s Office said in a statement following the signing of the pact.

While no further details have been disclosed, the partnership reportedly “encompasses all military means,” ranging from armed forces and nuclear cooperation to intelligence sharing.

Pakistan has even openly declared that it “”will make available” its nuclear program to Saudi Arabia if needed.

However, experts maintain that Pakistan’s ability to provide a nuclear umbrella to Saudi Arabia is dubious, as its longest-range missile cannot reach most potential threats to the country.

“The deal’s military value appears negligible beyond its symbolic photo-op,” Brown told The Algemeiner. “Pakistan lacks the capability to project power over 2,600 miles to Saudi Arabia.”

The pact is also designed to strengthen Saudi Arabia’s long-term defense autonomy, with defense industry collaboration, technology transfer, and military co-production and training, among other key initiatives.

Although the Saudi-Pakistani relationship has long been close, Brown explained that mutual support between the two nations has faced significant limitations.

“This new mutual defense pact is likely to remain a symbolic agreement, with its main applicability in nonbelligerent arenas, such as training and procurement,” he told The Algemiener.

Experts have also noted that the new pact could heighten regional tensions, strengthening Saudi Arabia’s defenses against Iran and its allies while also signaling its strategic posture toward Israel.

Yet, Brown argued that it makes little sense to suggest the pact is directed at Israel, given there is no realistic prospect of conflict between the Jewish state and either Saudi Arabia or Pakistan, whereas Iran remains far more active against both countries.
