The recent terror attack in Moscow shocked the international community and reiterated the fact that such terror attacks by Jihadists have neither disappeared nor diminished. Besides the loss of lives, casualties, and economic and social loss the attack caused, it also reopened the question of whether state actors or governments can respond adequately to these tactics of non-state actors. Terrorism is a global scourge that has spared none- be it the United States of America, Russia, or India. However, there is no commonly accepted definition of what constitutes terrorism, owing to the differences in interpretation by various states, based on calculations of their national interests. In 2001, when the US launched the global war on terror, it was accepted by most countries of the world, including Russia and China, which currently are at loggerheads with the US.
