In short, India required an asymmetric treatment of the two countries in the withdrawal arrangements, regarding Pakistan as an 'aggressor', whereas Pakistan insisted on parity. The UN mediators tended towards parity, which was not to India's satisfaction. In the end, no withdrawal was ever carried out, India insisting that Pakistan had to withdraw first, and Pakistan contending that there was no guarantee that India would withdraw afterwards. No agreement could be reached between the two countries on the process of demilitarisation.
