Answer 1

1965

The 1965 war between India and Pakistan was the second conflict between the two countries over the status of the state of Jammu and Kashmir. The clash did not resolve this dispute, but it did engage the United States and the Soviet Union in ways that would have important implications for subsequent superpower involvement in the region

The dispute over this region originated in the process of decolonization in South Asia. When the British colony of India gained its independence in 1947, it was partitioned into two separate entities: the secular nation of India and the predominantly Muslim nation of Pakistan. Pakistan was composed of two noncontiguous regions, East Pakistan and West Pakistan, separated by Indian territory. The state of Jammu and Kashmir, which had a predominantly Muslim population but a Hindu leader, shared borders with both India and West Pakistan. The argument over which nation would incorporate the state led to the first India-Pakistan War in 1947–48 and ended with UN mediation. Jammu and Kashmir, also known as “Indian Kashmir” or just “Kashmir,” joined the Republic of India, but the Pakistani Government continued to believe that the majority Muslim state rightfully belonged to Pakistan.
