Sri Aurobindo did mention that the Atom bomb was ‘given’ prematurely to man because of the exigency of the war. Though the process used in this weapon is asuric (by splitting) yet it was used for daivic purposes as the then American President and the British and French were used for the divine purposes. But later the hydrogen bomb came into being which relies on the energy of fusion and is more in the category of divya ashtra. However whether the process is Asuric or Daivic, a weapon is a weapon and can be used by any forces capable of using it like Meghnad used Shakti ashtra as well as Brahmashtra in the Ramayana and Aswathhama used Narayan Astra and Brahmastra in the Mahabharata war.
