The Pakistan–Iran relationship and the changing nature of regional and domestic security and strategic interests

The Pakistan–Iran relationship has been evolving over time. Ties between the two neighbours have been shaped by bilateral security concerns and strategic interests, as well as flux in the political identities of the two states. Pakistan and Iran were strong allies during the time of the Shah regime, as they had a harmonious political outlook and shared membership in the American-led political block during the Cold War. With the Islamic revolution, Iranian national identity underwent a radical change and gave birth to a political vision that was confrontational in essence. Diverging geopolitical interests and alignments in the region moved the two nations further apart. After the withdrawal of Soviet troops from Afghanistan, both sides backed different groups, and the bilateral relationship became further estranged owing to Pakistan’s support for the Taliban regime, which persecuted Afghan Shi’ites and was also involved in the killing of Iranian diplomats. The Iranian security accord with India, as well as Pakistan’s strong ties with Saudi Arabia, further contributed to making the relationship complex and uneasy. Burgeoning security threats across the border from anti-Pakistan insurgents of the Balochistan Liberation Army and anti-Iran insurgents of Jundullah and Jaish Al-Adl have complicated the relationship between the security establishments on both sides. Furthermore, attempts to politicise Pakistan’s Shi’ite community and instances of sectarian violence inside Pakistan have made both states wary of each other. These developments have been critical in impeding efforts to enhance ties in the economic and energy fields. Yet, these differences have not led both states to increasingly confront each other, as both sides fully realise the near-disastrous consequences of such a conflict. Nonetheless, they have also failed to develop a mechanism to address bilateral issues; thus, a tense competition epitomises the state of bilateral affairs. However, as the Pakistani institutions and government have started to change their strategic outlook towards the region, new opportunities are emerging for the improvement of the bilateral relationship.
