And Pakistanis were doing a genocide against Hindus and Sikhs at that time. Those were partition times.
Regardless what ever justification you might give for your invasion Kashmir. You are afterall invaders need to leave Kashmir.
So, the princely state of J&K is now analogous to the British provincial territory of Punjab? Punjab was divided by the British. *Some small fiefdoms did get to choose left or right but these were peripheral fiefdoms whose decisions were straightforward with no objection from the inhabitants.
J&K was a whole princely state, wherein the inhabitants were hostile to the chieftain (particularly in Jammu, see below), which was accounted for by Golwalkar and Singh in their meeting 18th Oct 1947.
The Muslim Conference of Jammu and Kashmir, declared itself to be in favour of accession to Pakistan on 19th Jul 1947. The Muslim Conference was popular in Jammu province and was an ally of Jinnah.
Singh and Golwalkar required a solution for this dilemma. There was only one - the villages of Amrey, Cheak, Atmapur and Kochpura had already been attacked on 14th Oct by RSS militias. Golwalkar and Singh knew that depopulation was the only means by which control could be exerted over the Muslim population and that is precisely what they plotted for. A particularly harrowing account from Nov, Jammu city, speaks of Muslims being besieged, with denial of food and water supplies, and laying down their arms to surrender and be promised passage to Sialkot by your highly moralistic army, only to be dragged from trucks at the border by RSS and brave sikh warriors and butchered.
By your own "historical" accounts, 21st Oct was the date when "tribals" crossed into J&K to relieve the Muslims of the state and fight back against sikh and RSS heroes. Thank the Lord they did, or the Jammu pogrom would have continued in regions that we snatched from you.
Gandhi, 25th Dec 1947: "The Hindus and Sikhs of Jammu and those who had gone there from outside killed Muslims. The Maharaja of Kashmir is responsible for what is happening there…A large number of Muslims have been killed there and Muslim women have been dishonoured."
Yet you are here drawing comparisons with Punjab province or even Bangladesh? This raises a further question. Do you even know what you're talking about?
