Macron: Europe's security depends on cooperation with Russia

French President Emmanuel Macron warned that European nations "cannot remain spectators" in the face of a potential nuclear arms race and urged them to restore trust with Russia.

"Europeans must realise collectively that in the absence of a legal framework, they could rapidly face a new race for conventional weapons, even nuclear weapons, on their own soil," Macron told military officers in a speech laying out France's post-Brexit nuclear strategy.

"There can be no defence and security project for European citizens without a political vision that seeks to progressively restore trust with Russia," Macron said.
