Speaking at the Nuclear Security Summit (NSS) convened at his own initiative, US president Obama has raised severe concerns over the misuse of Nuclear weapons by terrorists. Expressing his fears that terrorist organisations like al Qaeda and ISIS could grab some nuclear material, he said that they could use it to kill innocent  people. "There is no doubt that if these madmen ever got their hands on a nuclear bomb or nuclear material, they would certainly use it to kill as many innocent people as possible," he said.

Obama has invited leaders from over 50 countries for NSS to discuss the safety of Nuclear weapons. He reiterated the need for clearing off the materials such as uranium and plutonium fuels, so that terrorists may not make their own dirty bomb with such ingredients. Obama has also took the occasion to raise his concern over ISIS. But he is happy with the present war with ISIS. “They’re losing their oil infrastructure and revenues. Their morale is suffering,” he said.
