India is already operating 5 nuclear plants and keeping them away from terrorists. We never refrained from sending rokets because of naxalites or terrorists. Development should never stop because of panic due to terrorism.
Did anyone ever avoided travelling on road because of accidents. Did anyone ever stop flying because of plane crashes. So is the case with Nuclear Energy.
If we are not prepared for the extintion of fossil fuels, all will remain will be utter darkness. Then nobody will terrorise us. Who will trouble a country which is already in deep crisis.
