What significant event occurred after the third war between India & Pakistan?

Since the Partition of British India in 1947 and subsequent creation of the dominions of India and Pakistan, the two countries have been involved in a number of wars, conflicts and military standoffs. A long-running dispute over Kashmir and cross-border terrorism have been the predominant cause of conflict between the two states, with the exception of the Indo-Pakistani War of 1971, which occurred as a direct result of hostilities stemming from the Bangladesh Liberation War in erstwhile East Pakistan (now Bangladesh).
