It is easy to react to these and other blasts. Especially in the light of knowledge that it is done by Muslim terrorist(irrespective of who sponsors). The backlash , communal riots, hindu extremism, or Bush lead war against Islam somehow do not stop it. If the politicisation continues eventually another partition like stae will come ,which no one is ready to suffer emotionally. So what is the answer--
Islam ,the way it is perceived by Muslims , has to change from within. Muslim Intellectuals as well as ordinary people will have to oppose the fundamentalists , stop all support to these mad jehadis, even at the risk of going against the restrictive teachings. Will have to beleive that love is no 'kufr'. and open up their minds to be tolerant. This is the only way as external force can only breed anger and violence. World history has shown enough.
