Read the passage and answer the question.

Soon after the partition, the two countries got embroiled in a conflict over the fate of Kashmir. The Pakistani government claimed that Kashmir belonged to it. Wars between India and Pakistan in 1947-48 and 1965 failed to settle the matter. The 1947-48 war resulted in the division of the province into Pakistan-occupied Kashmir and the Indian province of Jammu and Kashmir divided by the Line of Control. In 1971, Indian won a decisive war against Pakistan but the Kashmir issue remained unsettled.

India's conflict with Pakistan is also over strategic issues like the control of the Siachen glacier and the acquisition of arms. The arms race between the two countries assumed a new character with both states acquiring nuclear weapons and missiles to deliver such arms against each other in the 1990s. In 1998, India conducted a nuclear explosion in Pokhran. Pakistan responded within a few days by carrying out nuclear tests in the Chagai Hills. But both governments continue to be suspicious of each other. The Indian government has blamed the Pakistan government for using a strategy of low-key violence by helping the Kashmiri militants with arms, training, money and protection to carry out terrorist strikes against India. The Indian government also believes that Pakistan aided the pro-Khalistani militants with arms and ammunition during the period 1985-1995. Its spy agency, Inter-Services Intelligence (ISI), is alleged to be involved in various anti-India campaigns in India's northeast, operating secretly through Bangladesh and Nepal. India and Pakistan have also had problems over the sharing of river waters. Until 1960, they were locked in a fierce argument over the use of the rivers of the Indus basin. Eventually, in 1960, with the help of the World Bank, India and Pakistan signed the Indus Water Treaty which has survived to this day.
