Macron proposes French nuclear extension, Ukraine troop deployment in case of ceasefire
www.lemonde.frIn a televised address to the French on Wednesday, the French president described Russia as a 'threat to France and Europe,' and said he wanted to confer with European allies on using France's nuclear deterrent to protect Europe.

FYI the EU is not about military, only about economics.
The UK has made the recent JEF with sweden and others for example, so no problem joining up militarily.
The EU is both. There are EU joint battlegroups and a stronger mutual defense clause in the treaties than NATO.
