The whole subcontinent, as well as the world, was shocked over the incident of Mumbai in which hundreds of people were killed. The two countries should learn a lesson from these incidents because both are beset by severe frustration among their people. And the reason is grave inequality in distribution of wealth. Nobody is justifying these acts of violence but the hard men at helm need to delve deep and learn some lessons from these incidents. Give people justice and there would be no violence. -SYED MUZAMMIL HUSSAIN, Islamabad, via e-mail, November 28.
