Prof M D Nalapat on the impending US sanctions on India on S-400 and how India should respond

China already has S-400s trained against India in Ladakh, which will severely constrain India's Air strategy in the event of a conflict. Plus S-400 has Chinese technology that can possibly snoop or disable when the S-400 is needed the most. Is India aware of these concerns? Prof M D Nalapat discusses these and more on how nasty emails about him and his character are being spread by some malcontents. A must watch!
