India responds as US intel chief says 'Pak poses nuclear threat to US'

India responded after US' intel chief Tulsi Gabbard said Pakistan along with Russia, China, North Korea and Iran are the biggest nuclear threat to the US. "They (Pakistan) have a history of clandestine nuclear nonproliferation, and statements like these again make it clear what kind of threat they pose to the world because of their clandestine nuclear operations," MEA said.
