The Importance of Europe's Realistic Approach to Russia

I don't quite understand what the Western Allied Warring is. Is it to stop something like a genocide in Ukraine? If so, I support 100%. But we've got to be realistic about Russia. NATO must be realistic. Europe must be realistic and not droppable. What would have happened earlier on in the Balkans if the Americans hadn't intervened? The EU is non-existent as a military entity, as a military power. It takes too long to get it up. Macron's army is a phantom. There was talk of historic change - but they backed off from most of that last week.
