Sir — The unity against terrorism by Pakistan’s political establishment after the Peshawar school attack is good for Pakistan and its neighbours. What you sow is what you harvest. Pakistan is suffering because its establishment supported terrorists. But the positive point is the uniting of the country for a cause, and this will certainly get results. like in Italy, the assassination of anti-mafia judge Giovanni Falcone in 1992 brought the whole of Italy together. Pakistan should set a deadline to obliterate the terrorists from its soil. This is the time for Pakistan to get things straight, otherwise that country will push itself into oblivion.
