A bit of historical correction here is in order .....
The Indian invasion of Indian Occupied Kashmir started much earlier than the Pathan intrusion and Pakistan Armys involvement. It was all started by and planned in meetings between rulers of Alwar, Kapurthala and Patiala etc with Maharaja of Kashmir with complete knowledge of Indian Hindu political leaders and their supporters in Indian government.
Many of us do not even know that after the pogrom in Punjab where Muslims were killed in millions in order to ethnically cleanse the areas and change the demography, where did these marauding Hindu and Sikh hordes were sent to? Indians wouldnt know or probably wouldnt want to acknowledge it these hordes were sent to Jammu to loot, rape, abduct and kill Muslims.
As planned, in the initial instance, they intended to ethnically cleanse areas of Jammu where Muslims were in minority. Between July and October 47, over 500,000 Muslims were thrown out of their homes, out of which 200,000 thousand were killed and about 300,000 were forced to emigrate to Pakistan. This was the first stage of this operation. The Pathans came to safeguard the Muslims from hordes of marauding Sikhs and fundamentalist Hindus and Pakistan Army moved in later when Indian Army had already invaded IOK.
I also have strong reservations about your other points as well.
