But the real problem in Kasmir is that Pakistan says that during 1947 when the ratio of Muslim : Hindu was 77:20 they wanted a plebisite (sort of opinion of Kashmiris) on whether they want to be a part of Pak or India. This plebisite was approved by UN, but has not taken place till now.
If this sort of plebisite is happening then whom would the Kashmir prefer - India or Pakistan.
Knowing very well that the J&K is full of Muslims, India didnt want to conduct plebisite. India claims that illegal Pakistanis are still in J&K. So, the plebisite will have no meaning.
Pakistan was pushing for plebisite till 1971 bcos they believed that J&K people will fully support them. But in 1971 war between India & Pak, it was noted that people of J&K were fully supporting India.
So, these terrorism is happening for decades.
But, legally all part of J&K belongs to india taking into account the ACCESSION AGREEMENT BETWEEN INDIA & KING HARI SINGH.
