I wrote this many times, the lowest blood price for subduing Russia is a NATO-wide airborne operation to behead Russian government, and a mother of all airlifts.
You fight a mafia state the way you fight a mafia, by simultaneously dismembering, and beheading it.
To completely subdue Russia, NATO has an option to do first strike nuclear attack with half of its combined arsenal along the lines I wrote above.
Russia is a hypercentralised state beyond imagination. Russia will cease its existence as a state if Moscow region is taken out, and the most limited counterforce attrition is ensured.
