France and Germany agreed to begin talks on a common nuclear umbrella in Jan 1997 as reported here in The Washington Post on Jan 25, 1997.
The post cites Le Monde- "Our two countries see themselves exposed to the same risks. We are ready to open a dialogue on the role of nuclear deterrence in the context of European defense policy." Says the document signed by Germany's Helmut Kohl and Frances Jacques Chirac on Dec. 9, 1996. France had clashed with the US under De Gaule and De Gaulle had pursued an independent nuclear deterrent. Chirac took up this stance in 1996 with nuclear tests in French Polynesia and offered to share its nuclear deterrent with Germany.
