Kargil war ( 1999 ) In 1998 , India carried out nuclear tests and a few days later , Pakistan responded with more nuclear tests giving both countries nuclear deterrence capability , although India had tested one hydrogen bomb which Pakistan lacked . Diplomatic tensions eased after the Lahore Summit was held in 1999 . However , the sense of optimism was short-lived since in mid-1999 Pakistani paramilitary forces and Kashmiri insurgents captured the deserted , but strategic , Himalayan heights in the Kargil district of India . These had been vacated by the Indian army during the onset of the inhospitable winter and were supposed to be reoccupied in spring . The regular Pakistani troops who took control of these areas received important support , both in the form of arms and supplies , from Pakistan . Some of the heights under their control , which also included the Tiger Hill , overlooked the vital Srinagar-Leh Highway ( NH 1A ) , Batalik and Dras
