Well, the Romans had that sort of scorched earth policy. Harm a Roamn citizen and you and your people would be punished big time. Every great empire that lasted had the same sort of policy. Get on board with us, pay your tribute/taxes, be cool and things will go well for you. Don't and you're up shit creek.
