The 1999 Kargil war, therefore, was the continuation of an unresolved problem. But this time, it involved the physical occupation of a sizeable piece of territory by Pakistan on the Indian side of the Line of Control; it took place between two democracies and putative nuclear weapon powers and could have escalated out of control. For these reasons it was exceptional.

The Kargil War, also known as the Kargil conflict, was an armed conflict between India and Pakistan that took place between May and July 1999 in the Kargil district of Kashmir and elsewhere along the Line of Control (LOC). In India, the conflict is also referred to as Operation Vijay which was the name of the Indian operation to clear the Kargil sector.

The cause of the war was the infiltration of Pakistani soldiers and Kashmiri militants into positions on the Indian side of the LOC, which serves as the de facto border between the two states. During the initial stages of the war, Pakistan blamed the fighting entirely on independent Kashmiri insurgents, but documents left behind by casualties and later statements by Pakistan's Prime Minister and Chief of Army Staff showed involvement of Pakistani paramilitary forces, led by General Ashraf Rashid.

The Indian Army, later on supported by the Indian Air Force, recaptured a majority of the positions on the Indian side of the LOC infiltrated by the Pakistani troops and militants. With international diplomatic opposition, the Pakistani forces withdrew from the remaining Indian positions along the LOC.
