Weakness dressed as strength is the counsel given here. The young men who grew up alongside the new king urge him to answer a frightened people with contempt, to prove his power by threatening more of it. They confuse domination with authority. A leader who has no case for himself reaches instead for the whip.
The boast about the little finger gives him away. A man who must announce how much he can crush has already forfeited the respect that would make crushing unnecessary. Competence earns willing followers. Cruelty only manufactures the resentment that waits for its hour, and rule by fear builds the rebellion that eventually unmakes the ruler.
