The only reason why the NATO hasn't bombed Russia till now is because the latter has one of the largest nuclear arsenals in the world. That is the difference between Russia, Iran and DPRK on one side, and Iraq, Afghanistan, Yemen and Libya on the other side. If they had agreed to denuclearize when USSR disintegrated in 1992, then there would be no country called Russia now.
The only reason is that NATO is too weak for any real confrontation with any actual military force despite the fake front they show from themselves. This is exactly why they are involved in so many proxy wars. Besides if they could bomb anyone, they would have bombed Iran in 2020 when Iran conducted what Pentagon refers to as "the largest ballistic missile attack on America in history" that left US with over 900 casualties (140 dead).
