I think Musharraf, Zardari and countless other such criminals are the production of a failed system that proved itself to be devoid of the spirit of human welfare. Now time is at hand for substitution of this system with the one to enable the world to serve humanity; the system of Islam. Only this can eradicate the difficulties being faced by the poor people of the world that can think only about their next meal and nothing else. So, please change the system, not the face. -SHAHID IQBAL RANA, Lahore, October 30.
