It all started when Pakistan violated the rules of the 'accession treaty' given by the Britishers and tried to capture a princely state i.e. J&K by force through a tribal incursion assisted by its army. Since the situation went out of control, the Maharajah asked India for help. India agreed to give a conditional support to the king, if and only if he agreed to accede J&K to India. After his affirmation, J&K became a part of India. But at this point of time, Pakistan army had already reached Srinagar. After a few days of war and heavy retaliation from Indian side, much of the lost land was recaptured. But then Pandit Nehru, the then prime minister of India out of nowhere decided to approach United Nations and cease fire was announced. The point where armies of both side stood at that point, is where they stand now (except in SiaChin glacier), which is known as the line of control or LoC; which is the most dangerous border in the world. Now the present state of Jammu and Kashmir is an Indian state for the Indians, India occupied Kashmir for the Pakistanis and a disputed territory for the World. In status quo, the actual state which India has claimed since 1947 is divided in three parts: the one controlled by Pakistan (known as Azad Kashmir in Pakistan and POK in India) which is approximately one-third of the actual state's area, the one controlled by India (known as the state of Jammu and Kashmir in India) which is almost half the area of the actual state and the rest is the territory controlled by China (as Aksai Chin and part of the Karakorum range which was gifted by Pakistan). The story of this issue has many climaxes, twists and turns. A feature film ends after the climax with a happy ending but this film seems to have no ending. The issue has come to a deadlock, which either party (India and Pakistan) cannot resolve. Now the question arises, If the war had continued, would we had reached a conclusion? Was cease fire necessary? Pandit Nehru thought that war between two 'brother states' just after their birth was a waste of time, resources and money. But same was with United Nations! Going in United Nations was then a 'failed strategy' because United States along with two other nations (which belong to the powerful security council) were against India's stance. Pakistan has never accepted India's control over Kashmir, it has claimed that the treaty of accession was signed under pressure by the king and hence it is not valid. Since 1947, this issue has taken a lot from both the countries in terms of blood,lives, money, emotions but given nothing.
Best thing for now is to leave the issue on our future generation on a positive note that they might find a solution that will be accepted by all. Time has healed many wounds, maybe it could heal a border problem, which actually isn't just a border problem.
