Former prime minister and Pakistan Tehreek-e-Insaf (PTI) Chairman Imran Khan has said that it was imperative for leaders and generals to take U-turns in order to identify and rectify their mistakes. Imran said the country’s institutions were weakened during the tenure of three military dictators. “If differences between the people and the army continue to grow, everyone will suffer. I can never see the army becoming weak. We cannot afford a weak army.
