That "Pakistan had violated the Stand Still Agreement first", besides others
Read the UN Resolutions .... They state:
"The question of the accession of the State of Jammu and Kashmir to India or Pakistan will be decided through the democratic method of a free and impartial plebiscite." ... and you still believe that the UN considers the "Instrument of Accession" as legally valid and complete ??? One word .. "delusional"
Anyway, here is an "Indian" source, just for your satisfaction:
Thus, an analysis of the circumstances surrounding the signing of the Instrument of Accession shows that the accession of Kashmir to India was neither complete nor legal, as Delhi has vociferously contended for over sixty years.

Yes, but the (alleged) Accession of Kashmir to India is different from accession of any other Indian Princely State (to India or Pakistan) as it is the only "accession" that has been placed before the UN Security Council for arranging a ratification or otherwise by the people of the State under the auspices of the United Nations. So far, it has not been ratified by the Kashmiris. And until and unless the Kashmiris, using their right to self determination in a referendum held under UN auspices, decide to ratify this accession, the UN won't consider
the accession caused through the so called "Instrument of Accession" as legally valid and complete ..... Do you get it now ?
