India and Pakistan have their own political and economic aims in Afghanistan since inception. The association between Pakistan and Afghanistan have always remained uneven. This is due to the convergence and divergence of interest of both the states. Indian factor has played its greater role in the strained relationship between both the states. Hostile Indian presence on the Afghanistan border is a matter of security concern for Pakistan. Taliban factor always remained a threat for India. India signed strategic partnership deal with Afghanistan and became the sixth largest donor to Afghanistan. Afghanistan is getting greater economic benefits from India and in return has provided its land for terrorist activities against Pakistan. Pakistan on the other hand has played very effective role in bringing Afghan Taliban and United states to the negotiation table for achieving peace in Afghanistan. This paper utilizes the classical realism theory to explain the political and economic interests of India and Afghanistan and also explains the strained Pak Afghan relations ever since due to the involvement of Indian factor. So this triad always remained in conflict and on trajectory of uneven relationship.
