Divergence and Divide
Shia – Sunni divide:Ayatollah Khomeini’s ultra-conservative Shiite regime in Iran and Sunni majority Pakistan’s Islamisation under dictator Gen Zia-ul-Haq led to the divergence.
US-Pakistan closeness:The Iranian revolution distanced the US and Iran, while the US drew Pakistan closer, generating distrust.
Arab Nations: The export of republican ideas of the Iranian revolution irked family-governed Arab nations, while Pakistan continued close relations with Arab nations.
Afghanistan:Iran supported the Northern Alliance against the Taliban, especially after attacks onPersian-speaking Shia Hazaras and Iranian diplomats in Mazar-i-Sharif in 1998.
Ups and downs of Reconciliation efforts
Benazir Bhutto Government: Visit in 1995, Import of Iranian Gas, Called Pakistan ” Brother in Islam”.
Musharraf Period: Military coup(1999) and soured relations.
2008-2013: Signing of Iran-Pakistan pipeline project under the Zardari government indicated improvement, but Pakistan’s Sunni Arab allies feared the Iran-led “Shi’ite triangle”.
Post-2013, the Pakistani Sharif government came closer to Arab allies to undo the Iranian tilt.
Strategic convergence:China has become most important strategic partner of both Iran and Pakistan.
Occasional border issues and minority rights continue to raise concerns between both nations.
