Ukraine's Nuclear Dilemma
In 1994, Ukraine's leaders gave up a formidable nuclear arsenal. But the country is now mired in war. We follow one young man who asks his fellow citizens if they'd have been better off keeping what is often dubbed the ultimate deterrent. His grandfather advocated disarmament as a government minister. So did William Perry, the US defense secretary tasked with overseeing the dismantlement process, who reflects on his work now that Russia threatens to use the most destructive weapon of all.
