There is no way to escape an apocalypse but to banish the nuclear weapons from the face of the earth. Countries nuclear-armed to the teeth, like the US and Russia, cannot hide or deny nuclear disparity. In fact, they are bereft of moral authority to prevent other countries from going ahead with nuclear programmes. They must lead by example and deactivate or destroy the nuclear arsenal in a phased but in a time-bound manner. Making the world free from nuclear weapons would be a wise thing to do to secure our continued existence on the planet evolved to support life.
