Deep mistrust continues to derail Iran-US diplomatic efforts

Efforts to resolve disputes between Iran and the United States repeatedly falter despite periodic attempts at dialogue, analysts say, pointing to an entrenched pattern of hostility that shapes how both governments approach negotiations.

The troubled history between the two nations—spanning from the 1979 revolution through decades of sanctions, regional proxy conflicts, and military posturing—has created deeply rooted policy frameworks that each side views as non-negotiable. Trust remains minimal, with both Tehran and Washington interpreting the other's actions through the lens of past confrontations rather than present possibilities.

This historical baggage manifests in concrete ways during talks. Iranian officials approach negotiations wary of perceived American duplicity, while American policymakers remain skeptical of Iranian compliance with any agreement. Previous diplomatic initiatives, including the 2015 nuclear deal and subsequent negotiations, have foundered when one side withdrew or reneged on commitments, reinforcing perceptions of bad faith on both sides.

Regional tensions compound these fundamental obstacles. Disagreements over Iranian support for militant groups, American military presence in the Gulf, and competition for influence across the Middle East create additional friction that seeps into nuclear and sanctions discussions. Without addressing these underlying strategic rivalries, experts suggest, even technically sound agreements face implementation challenges.

For substantive progress to occur, analysts note that both countries would need to move beyond zero-sum frameworks that treat any concession as weakness and any Iranian initiative with reflexive suspicion. Whether either government possesses sufficient political will to attempt such a shift remains uncertain.
