Former CIA Director and United States Secretary of Defense Robert Gates joins One Decision's Christina Ruffini and former MI6 Chief Sir Richard Dearlove to discuss global security challenges facing the West and its allies. Gates describes the challenges as "more perilous than we've probably faced since World War II." They also discuss what's at stake for the Taiwanese, Russia's strategy in Ukraine, Iran's brittle regime, far-right populism in Europe, and whether America should build an Iron Dome. Plus, Sir Richard shares an anecdote from former UK Prime Minister Margaret Thatcher.
