U.S. Sen. Lindsey Graham (R-SC) has called for a review of Pakistan's suitability as a mediator in U.S.–Iran negotiations following reports of hidden aircraft.

The challenge to Pakistan's neutrality comes at a critical juncture in Middle East diplomacy. If a mediating nation provides military sanctuary to one party, its ability to act as an impartial broker is fundamentally compromised.

Graham's concerns stem from a CBS report indicating that Iranian aircraft were secretly moved to Pakistani air bases during a conflict with Iran [3]. The senator said that such actions undermine the credibility required for a country to facilitate high-stakes diplomatic talks between Washington and Tehran.

"It may require a complete reevaluation of the country's mediator role," Graham said [2]. When asked about the possibility of such arrangements, Graham said, "I wouldn't be surprised" [1].

This scrutiny follows a period of intense diplomatic activity between Islamabad and Tehran. Reports indicate that Iranian Foreign Minister Abbas Araghchi made three visits to Pakistan within a 48-hour window [4]. The frequency of these high-level meetings has further fueled suspicions regarding the depth of the bilateral relationship, and its impact on mediation efforts.

Graham said that the sheltering of military assets suggests a level of cooperation that precludes impartiality. The senator's public questioning of Pakistan's role signals a potential shift in how the U.S. may approach the use of third-party intermediaries in the region.

Pakistan has not officially responded to these specific allegations regarding the air bases. However, the reports have sparked a broader debate among U.S. lawmakers about the reliability of regional partners who maintain complex security ties with adversaries of the U.S.

"It may require a complete reevaluation of the country's mediator role."

The questioning of Pakistan's neutrality by a high-profile U.S. senator complicates the diplomatic architecture of the Middle East. If the U.S. loses confidence in Pakistan as a neutral venue or facilitator, it reduces the available channels for indirect communication with Iran, potentially increasing the risk of miscalculation and prolonging the current diplomatic deadlock.
