India–Pakistan relations

India and Pakistan have a complex and largely hostile relationship that is rooted in a multitude of historical and political events, most notably the partition of British India in August 1947. Two years after World War II, the United Kingdom formally dissolved British India, dividing it into two new sovereign nations: the Union of India and Pakistan. The partitioning of the former British colony resulted in the displacement of up to 15 million people, with the death toll estimated to have reached between several hundred thousand and one million people as Hindus and Muslims migrated in opposite directions across the Radcliffe Line to reach India and Pakistan, respectively. In 1950, India emerged as a secular republic with a Hindu-majority population. Shortly afterwards, in 1956, Pakistan emerged as an Islamic republic with a Muslim-majority population. While the two South Asian countries established full diplomatic ties shortly after their formal independence, their relationship was quickly overshadowed by the mutual effects of the partition as well as by the emergence of conflicting territorial claims over various princely states, with the most significant dispute being that of Jammu and Kashmir. Since 1947, India and Pakistan have fought three major wars and one undeclared war, and have also engaged in numerous armed skirmishes and military standoffs; the Kashmir conflict has served as the catalyst for every war between the two states, with the exception of the India–Pakistan war of 1971, which instead occurred alongside the Bangladesh Liberation War, which saw the secession of East Pakistan as the independent country of Bangladesh. It resulted in a large displacement of Pakistan's Hindu minority. The India–Pakistan border is one of the most militarized international boundaries in the world. There have been numerous attempts to improve the relationship, notably with the 1972 Shimla summit, 1999 Lahore summit, and the 2001 Agra summit in addition to various peace and co-operation initiatives. Despite those efforts, relations between the countries have remained frigid as a result of repeated acts of cross-border terrorism sponsored by the Pakistani side and alleged subversive acts sponsored by India. The lack of any political advantages on either side for pursuing better relations has resulted in a period of "minimalist engagement" by both countries. This allows them to keep a "cold peace" with each other. Northern India and most of modern-day eastern Pakistan overlap with each other in terms of their common Indo-Aryan demographic, natively speaking a variety of Indo-Aryan languages (mainly Punjabi, Sindhi, and Hindi–Urdu). Although the two countries have linguistic and cultural ties, the size of India–Pakistan trade is very small relative to the size of their economies and the fact that they share a land border. Trade across direct routes has been curtailed formally, so the bulk of India–Pakistan trade is routed through Dubai in the Middle East. According to a BBC World Service poll in 2017, only 5% of Indians view Pakistan's influence positively, with 85% expressing a negative view, while 11% of Pakistanis view India's influence positively, with 62% expressing a negative view.
