As the country continues to witness agitation surrounding the 'Agnipath' recruitment scheme, National Security Advisor of India Ajit Doval, while commenting on the scheme said that change is a prerequisite if we have to prepare for the future. During an interview with ANI's Smita Prakash, NSA Doval said, "Security is a dynamic concept. It cannot remain static, it is only in relation to the environment in which we have to protect our national interest and national assets. The whole war is undergoing a great change. We are going toward contactless wars. If we have to prepare for tomorrow, then we have to change." (Video Credit: ANI)
