The Indo-Pakistani War of 1965 and subsequent War of 1971 put a hold on matches between the two sides that lasted till 1978, when India toured Pakistan and cricket between the two countries resumed for a brief period. In the post-1971 period, politics became a direct factor in the holding of cricketing events. India has suspended cricketing ties with Pakistan several times following terrorist attacks or other hostilities. The resumption of cricketing ties in 1978 came with the emergence of heads of government in both India and Pakistan who were not directly connected with the 1971 war and coincided with their formal initiatives to normalise bilateral relations. Shortly after a period of belligerency during the Operation Brasstacks war games, Pakistani president Zia-ul-Haq was invited to watch the India–Pakistan Test being played in the Indian city of Jaipur. This form of cricket diplomacy has occurred several times. Pakistan toured India in 1979, but an Indian tour of Pakistan in 1984 was cancelled mid-way through the series due to the assassination of Indian Prime Minister Indira Gandhi.
