Just imagine a situation. India is in war against her hostile neighbour. And the news has come that the neighbour continuously beaten conventionally arrenging to nuke India. What should India do? It will lunch its nuclear missile before the enemy to save millions of Indians or it will stick with no first use policy and wait for the enemy missiles to see its own citizens to be slaughtered before going for retaliation. Is the image of a good boy to international community is more precious than life of millions of Indians? countries like US, UK mentioned to use nuclear weapon in defencive purpose, then why India should not review its no first use policy when its surrounded by a country with ambiguous and unreliable 'no first use policy' and another blatuntly threatening to nuke India if necessary. What do you think?
