Pakistan allowed Iranian military aircraft, including a reconnaissance RC-130 variant, to use Nur Khan Airbase during the U.S.-Iran conflict to shield them from American airstrikes — a move confirmed by multiple outlets citing U.S. officials. This creates a diplomatic problem because Pakistan has been publicly positioning itself as a neutral mediator in the U.S.-Iran conflict while simultaneously providing material military support to one side. The disclosure raises questions about Pakistan's credibility as a mediator and its ability to balance relations with both the U.S. and Iran amid escalating regional tensions.
