Sir: After the Peshawar tragedy, the government of Nawaz Sharif stands fully exposed. The writer’s criticism of Nawaz Sharif is based on facts. He has rightly challenged his leadership at the most critical juncture in Pakistan’s history. He lacks the vision of setting priorities and instead relies on old, corrupt hands and a wrong selection of advisers. Is the security of the country not more important than mega projects? Is the security of the country not more important than confrontation with the army? Is our security not more important than fruitless foreign trips? Effective leadership is not about making speeches or being liked. Leadership is defined by results, not attributes. Mukhtar Ahmed Karachi
