Europe are already fighting Russia. Russia has made scores of "hybrid war" attacks throughout Europe and GB, including attempted bomb-laden drones at Leipzeig airport, cutting numerous undersea cables, and even "errant" drone attacks. They are also likely behind amplifying the current unrest in France.

EU politicians don't want to acknowledge the ongoing war because they think it would be an escalation and they also have a fear of 'Russia breaking up'. Other than the Baltic states, they don't realize the only way to stop it is push back, hard and fast, as Ukraine is doing. The Russian military is low-capability and declining, reliant now on North Korea and Iran, and the economy is sliding. The reality is little could be better than Russia breaking up and finally abandoning it's imperial ambitions, which are still active today.
