India is so call secular not based on religion.. Quaid e azam told you we are 2 different world cant live together. PM from other religion can happen in India not in Pak.Sikhs make up 1.73% of Indian population.... wasn't one of the PMs of India a Sikh (Manmohan Singh).
India's also had 4 Muslim presidents and 1 Sikh president.
97% of the population is Muslim, so I wouldn't be surprised if minorities are not represented much in the army. Plus there's no culture in Hindus and other such minorities to join the army. There have been a lot of Chrisitans though, and they've served well.Miniscule number of minorities in your armed forces. Hence just a token presence.
This is the constitution of Pakistan and the same is not the point to attempt a shame & blame against Pakistan. The argument is not even considerable unless majority decides or someone think to please the other side.non muslim doesn't have a right to become president or prime minister in Pakistan.
