Not entirely true Jinnah gave the order but Pakistani military order didn't want to directly fight India. Also the tribals were repulsed back from Srinagar. Indian forces after Kashmir signed Instrument of Accession were rushed to Kashmir under 5hrs.Not possible because the colonial army wont let u. In 48 they stopped mujahideen from going further, evwn though the momentum was on our side and we could have easily taken all of Kashmir and laddakh.
Again in 62 we didn't attack because colonial slaves disnt want to damage india and take Kashmir.
The attack seems to have originated from Poonch area and the major operating centre was present there, Indian army repulsed the attackers from there too.
