The strange stability between Tehran and the Taliban

Key Points:

• Despite deep-rooted sectarian differences between the Sunni Taliban and Shiite Iran, practical political interests and mutual necessity have driven a pragmatic relationship over the past two decades, particularly after the Taliban's return to power in 2021.
• Iran has maintained engagement with the Taliban without formal recognition, viewing Afghanistan as a critical neighbor for managing border security, drug trafficking, refugee flows, and regional stability, while also benefiting economically from trade and transit routes.
• Shared opposition to the US military presence in Afghanistan and common security concerns, including threats from ISIS-Khorasan and regional militancy, have fostered closer cooperation between Tehran and the Taliban despite ideological divides.
• The Taliban's deteriorating relations with Pakistan have increased their reliance on Iran, which in turn leverages this dependency to maintain influence, although mutual distrust persists due to differing religious doctrines and geopolitical rivalries.
• While economic ties and security cooperation have strengthened, unresolved issues such as refugee management, water rights, and Tehran's withholding of formal recognition underscore the relationship's pragmatic but fragile nature.
