Since when did Wikipedia become an official source?Your understanding of events is something repeatedly trumpeted by Indian media to spread lies, but the truth is totally different, and sadly, Pakistanis are not fully aware either, so lies live on.
1. The above was superseded by the UN Security Council resolution 80 adopted on 14th March 1950.
This resolution supported the recommendations in a report by General Andrew McNaughton, who had made the recommendations because of the stalemate in Jammu and Kashmir.
2. Under resolution 80 both countries were to reduce their forces simultaneously and only maintain a minimal force for the purposes of internal security. It did not require Pakistan or India to take the first steps, both were required to act concurrently and mutually.
3. India was a member of the Security Council when this resolution was passed but had abstained, it did not oppose the resolution, which in effect is a quiet approval, if India was explicitly opposed, it would have voted against the resolution.
You can find the actual resolution and the report by visiting the UN website.
Here is the official UN source for the resolution 80.
It only thanks India and Pakistan for maintaining ceasefire, urges them to continue ceasefire and recommends further negotitations between the 2 countries.
