The dissertation entitled “Role of Opposition against Zulfikar Ali Bhutto and against Ziaul Haq: a comparative study” provides a comprehensive account of the role of two opposition movements; first against Bhutto and the second against Gen. Zia. In Bhutto’s ascendency to power establishment played a mixed role as it had to bring him in power in the wake of military disaster of 1971. But after assuming power he could hardly maneuver between the civil and military leadership to steer the ship of democracy on a sustainable track. Eventually he met a tragic end at the hands of same forces that earlier brought him into power. In the case of Gen. Zia the opposition played a reverse ball game. The role of opposition movement (PNA) against Bhutto, role of various key players, “behind the curtain” forces against the popularly elected government of Bhutto was quite obvious in bringing down the popularly elected government of Zulfikar Ali Bhutto. On the contrary, the struggle of opposition movement (MRD) against Zia, role of various segments of Pakistani society in the movement for the restoration of democracy and rule of law led to an extent in restoration of democracy in the country. In fact, Bhutto came in power as a result of a popular movement of 1968-69 which mounted against the then President Ayub Khan. This movement, for the first time in the history of Pakistan, challenged the status-quo. After assuming power as a popular leader of the country he introduced egalitarian reforms which further antagonized opposition among the forces of status quo. The study explored that opposition in connivance with other forces overthrew the democratically elected government. Ironically, the then opposition turned a democratic country into dictatorship; an anti-capitalist country turned into a staunch ally of US-led Jihad (war) against USSR in Afghanistan and adopted a pro-US foreign policy. Bhutto, despite being a feudal himself introduced a number of egalitarian reforms and challenged the interests of the elitist classes including civil-military establishment, industrial elite, feudal class and other elitist groups. These groups with their class interest supported to launch a strong movement against Bhutto and consequently succeeded to overthrow him with the help of military junta. In contrast the movement against Zia was launched by people of Pakistan for the establishment of democracy and rule of law in the country. Almost all opposition political parties and progressive segments of Pakistani society played an important role to render great sacrifices in the movement against Zia. The role of political workers, lawyers, students, women and other segments of society has been instrumental against the dictatorial regime of General Zia. Although the movement could neither bring the dictator down nor succeeded to bring back the process of change started by the 1968-69 movement against the strata of ruling elite, nor it could bring back the process of egalitarian reforms initiated by Bhutto regime.
