The Iranian nuclear deal, if implemented, could alter many strategic equations in West Asia, including Iran’s relations with neighbors India and Pakistan.
The nuclear deal is sure to give Iran an upper hand in West Asia. However, strengthening Indian-Iranian relations may not bode well for Iranian-Pakistani relations.
Undivided India and Iran have shared long historic and cultural ties dating back from the Indus Valley Civilization. Cultural and economic ties however, deteriorated during the period of Aurangzeb’s rule in India and worsened during the British colonial rule in India. Further, with the partition of India and Pakistan in 1947, after India lost geographic contiguity with Iran, Pakistan became a crucial factor in determining relations between Iran and India.
