When Ukraine war started for example, there were many lists of oligarchs, "Putin's circle" cieculating around. These would lead to, even when there were no sanctions, activism against these names and avoidance of doing business with these names.

Divide & Conquer: (1) Put list of your enemies names on a wall, making then more vulnerable. When they are unable to appear neutral or allied to someone else than your enemy again, they will become socially isolated. (2) Cause some reason why everyone should be scared of being an ally of your enemy. (3) Take down your enemy, knowing no one will come in defense of them.

Note that my first example does not refer to the assasinations of Russian oligarchs, and I only speak of targeting as a tactic of Divide & Conquer strategy.
