Pakistan's role as a mediation venue for US-Iran talks depends on demonstrating control over its territory and freedom from proxy pressure.
Active border conflict with Afghanistan—a country where Iran maintains significant influence through Shia militias and intelligence networks—suggests either that Pakistan cannot contain spillover from the broader Middle East escalation or that it is being tested by Iranian proxies to signal the cost of hosting US-Iran negotiations.
If Pakistan's mediation efforts fail due to domestic instability, the diplomatic off-ramp currently being constructed collapses, and the conflict enters a phase with no negotiation track outside direct military pressure.
Pakistan's ability to host and mediate US-Iran negotiations depends on its capacity to maintain stability on its own borders and project neutrality.
Active Pakistan-Afghanistan fighting undermines Pakistan's credibility as a neutral venue and signals that Islamabad cannot isolate its own territory from the broader regional conflict.
If the clashes persist or escalate, Pakistan may lose the diplomatic leverage it has gained by positioning itself as a de-escalation hub—and the US and Iran may redirect talks to a third venue, reducing Pakistan's geopolitical influence in the current crisis.
The article does not specify the scale, location, or cause of the border clashes—whether they are isolated incidents, part of a pattern, or triggered by spillover from Middle East operations.
