Are we heading for a World War?

The 4 most prominent reasons why there can be a Nuclear War are-
1.Israel-Palestine isuue
2.Dictator of North Korea
3.ISIS
4.The Kashmir issue

In this post I would like to get a deep insight on what the Kashmir issue is-

The Kashmir dispute heads back to 1947.The The Kashmir dispute dates from 1947. The partition of the Indian sub-continent along religious lines led to the formation of India and Pakistan. However, there remained the problem of over 650 states, run by princes, existing within the two newly independent countries.

In theory, these princely states had the option of deciding which country to join, or of remaining independent. In practice, the restive population of each province proved decisive.

The people had been fighting for freedom from British rule, and with their struggle about to bear fruit they were not willing to let the princes fill the vacuum.
But his hopes of remaining independent were dashed in, as Pakistan sent in Muslim tribesmen who were knocking at the gates of the capital Srinagar.

Hari Singh appealed to the Indian government for military assistance and fled to India. He signed the Instrument of Accession, ceding Kashmir to India.

Indian and Pakistani forces thus fought their first war over Kashmir. India referred the dispute to the United Nations . In a resolution dated the UN asked Pakistan to remove its troops, after which India was also to withdraw the bulk of its forces.

Once this happened, a "free and fair" plebiscite was to be held to allow the Kashmiri people to decide their future.

India, having taken the issue to the UN, was confident of winning a plebiscite, since the most influential Kashmiri mass leader, Sheikh Abdullah, was firmly on its side. An emergency government was formed with Sheikh Abdullah as the Prime Minister.

Pakistan ignored the UN mandate and continued fighting, holding on to the portion of Kashmir under its control. On a ceasefire was agreed, with 65 per cent of the territory under Indian control and the remainder with Pakistan.

The ceasefire was intended to be temporary but the Line of Control remains the border between the two countries.

The current standing of the respective governments of India and Pakistan are-

India-Kashmir is a integral part of India.
Pakistan-Kashmir is a integral part of Pakistan.

Thus both the Nuclear countries have a conflicting stand on the Kashmir issue and consequently there has been constant ceasefire violations on the border,this might lead to war if the conflict stands undressed.
