Despite opposition from domestic interest groups, US President Barack Obama has reportedly been mulling a no first use policy for the country's nuclear arsenal.

As the world's sole superpower, even in terms of conventional weaponry, such a policy will by no means compromise its military supremacy. Instead, it would cater to people's desire for peace, and help reduce the chance of this fearful power of destruction being unleashed again.

Yet ironically, Japanese Prime Minister Shinzo Abe, the leader of the only country that has suffered an attack by nuclear weapons, has opposed the idea.
