European nations wanting “insurance” against Russia are looking to France and Britain to share their nuclear deterrents.

European countries that spent decades sheltering under America’s nuclear umbrella are now openly discussing a new form of protective alliance against Russia built around French and possibly British atomic weapons.

Leaders in Sweden, Norway, Germany and the Netherlands — some of Europe’s most pro-American countries — have publicly confirmed in recent days that they’re holding conversations about a European nuclear deterrent to complement the American version.
