Tyrants never worry about the costs. They never have to pay them, their subjects do. It is never wise to assume such a benevolence dwells in the mind(s) of a tyrant. History shows that tyrants always go for broke. They are always ruthless. They should never be underestimated and always opposed before it's too late. Appeasing tyrants is a sure course to ruin. They should be made to pay soon after they show their face.
