@meltedcheese that is what Russia wants us to think. But I call that madman theory: They want us to believe, that Putin is some evil super villain who is ready to destroy the world. The only problem is, the Russians have children too, and just like us, they would like to see those children again.
NATO has 4223 nuclear weapons, and while Russia needs to strike every power center accross the entire democratic world to win, just one nuke on Moscow would change Russia for good.
