Russia has unleashed a new wave of military innovation from 20 or so of the highest tech nations on Earth (of which they are definitely not one). The bottom line is if nukes weren't enough to stop war with mutually assured destruction, other means will enter the fray to make war even more ridiculous and suicidal than ever. Believe me, there are MANY more ways to destroy a nation than to melt it with a radioactive glaze that kills all life. If russia didn't have a nuclear arsenal, this war would have never started but if it did, would have been over in a few weeks.
