According to the views of Russian scholar Anatol Lieven, the Pakistan Armed Forces play a vital role in keeping the Pakistani state together, promoting a spirit of unity and nationhood, and providing a bastion of selfless service to the nation. As an institution, the armed forces have been integrated into Pakistani civil society since the establishment of the country in 1947. The military has been involved in building much of the country's infrastructure (such as dams, bridges, canals, power stations, and energy projects) and civil–military input from all sections of the armed forces has helped to build a stable society and professionalism in the armed forces.
