The USSR were high on assassinations of their own people if that's what you're asking. Obviously it's not a brilliant strategy because it just means that the people who are the most talented are going to not want to rise to the top or going to want to the rise to the top in other countries.
It's ultimately self-defeating, which of course is why only Putin thinks it's a swell idea.
Agreed, Putin is worried about support at home and also needs people abroad to think Russia is strong and can continue the Kremlin's barbaric war. The economist didn't want to cook the books like Putin suggested, so they were murdered.
