French President Emmanuel Macron has called for a debate on European security, including missile defense and nuclear capabilities, in response to Russian threats.

Macron proposes the idea of a European nuclear deterrent, sparking controversy over French strategic autonomy and sovereignty.

While there's no plan to share the decision-making on nuclear strikes, the concept of France sharing nuclear capabilities within Europe is not dismissed, though it would require bilateral agreements.

Macron's initiative aims to bolster the credibility of European defense, with France leading, as Germany also moves towards establishing a European missile defense system.

The push for European defense autonomy is increasingly relevant due to the geopolitical shifts following Russia's invasion of Ukraine and the possibility of an isolationist US leadership in the future.
