French President Emmanuel Macron requested a government plan to secure critical infrastructure and sensitive defense sites against potential drone and cyber attacks following an intensification of Russian hybrid threats. During a closed-door briefing at the Élysée with party leaders and 2027 presidential candidates, Macron stated that Russian actions against Europeans would not go unanswered, though the specific deterrent responses remain classified. The meeting included Prime Minister Sébastien Lecornu and senior intelligence officials to ensure future national leaders have access to restricted security data.

The security summit also addressed an energy crisis driven by international wars and the closure of the Strait of Hormuz. Macron intends to convene the G7 during France's upcoming presidency to discuss strategic stockpiles, production capacity, and exports. To lower domestic fuel costs, France is coordinating with the European Commission on gas storage flexibility and promoting electrification to reduce hydrocarbon dependence.
