Context

“In this way, the prince whose alliance we renounce is cut off from our community, and is no longer one of the members which compose it. No greater insult can be offered a prince, than to renounce his alliance, and no greater honour can be conferred upon him, than to enter into one with him. Nothing on earth adds more to our honour, and is really more useful, than to see others always careful of our preservation. But, in order that the alliance may be binding, it must be just: thus an alliance contracted between two nations to oppress a third is not lawful; and there would be no guilt in breaking it. It is by no means honourable or dignified in a prince to ally himself with a tyrant.” source
