Nothing in the language of the Simla Agreement "supersedes" the UNSC Resolutions on Kashmir, as I clearly established in the thread you linked to earlier. In fact, the language of the Simla Agreement supports the UNSC Resolutions as a "mutually agreed upon means of dispute resolution".
And you and some others do not cease to amaze me (actually, you don't - its pretty much par for the course with you lot) with your inability to engage in an actual debate and offer rational rebuttals, instead of meaningless one liners.
The tense should be present - whether you want to argue mutually agreed upon or "to the satisfaction of the UNSC", the fact remains that UNSC Resolutions subsequent to the initial resolutions moved away from the "conditions" of a demilitarization by Pakistan first, and since India continues to renege on her commitment to the UNSC resolutions, which brings up the point of whether ANY commitment India makes should be trusted or not, progress on fulfilling the conditions leading to a plebiscite according to the UNSC resolutions cannot begin.
The onus here is on India to act as a responsible member of the international community, and abide by her commitment to the UNSC Resolutions on Kashmir.
