Catherine Field: France Correspondent on France's plan to increase nuclear arsenal, geopolitical conflicts

France is increasing its nuclear arsenal for the first time in decades.   It will also significantly intensify nuclear weapons cooperation with eight European allies, French President Emmanuel Macron announced.  He says the “period of geopolitical upheaval” means France, the EU’s only nuclear power, must strengthen its deterrent in the face of multiple threats.  France Correspondent Catherine Field told Mike Hosking that in the past, France maintained a policy of “strict sufficiency” for its nuclear warheads, but that policy has been removed.  She says they’re not sure how many warheads will be in the supply, as the details have been light.  LISTEN ABOVE  See omnystudio.com/listener for privacy information.
