You have to the higher ups in the Party will decide to get rid of Jong just for self-preservation but Stalin was able to get away with his purges for over 20 years.
Even then Beria finally had enough and did away with him. Of course, it didn't save Beria in the end.
Yeah but eventually Stalin was purged.
You have to remember every time he purges someone, it means upward mobility for someone lower on the pole. So he gets support there.
Then of course dictators encourage rivalries among their followers. Combine that with the terror of not knowing who to confide in to get a conspiracy going, and it’s not surprising they’re able to keep these reigns of terror going.
