Union Defence Minister Rajnath Singh addressed at NDC Convocation ceremony in Delhi on September 26. He said “The recent events in Afghanistan have highlighted the reality of our times. The only certainty about evolving geopolitics is its uncertainty. Changes in state boundaries may not be as frequent today as they once were. However, fast transforming structure of states and the influence that external powers can have on it is clearly evident. These events raise questions on very role of power politics and use of terrorism as a tool to change state structure and behaviour.”
