This bears repeating. Russia has bee actively engaged in low-intensity warfare with the west for decades, and has single-handledly escalated their aggression towards the west in general but western Europe in particular for the last couple of years to the point they overtly and very publicly threaten the world with all sorts of attacks and global annihilation.
Once Russia tries to casually float a massive bomb right into your doorstep, only a massive moron would not mitigate the risk presented by Russia, even if considered implausible.
