A new documentary calls for a world without nuclear weapons. We go deep into "Countdown to Zero."
There are 23,000 nuclear weapons in the world, and we don't know where all of them are. Some have been lost – presumed stolen – out of fallen planes and sunken ships. Some are in the American Midwest, trained across the map at Russia. Some are in Russia, trained back at major US cities.
The new documentary “Countdown to Zero” makes a case for complete disarmament, before the nine nuclear nations wreak havoc in the world, or leak their atomic secrets to lawless hands. We hear their case – and test it.
Lucy Walker, documentary filmmaker, is director of “Countdown to Zerø.” Her previous films include "Waste Land," "Blindsight," and "Devil's Playground."
