The quote highlights the powerful and persuasive nature of a woman's charm, as expressed through her lips. The speaker suggests that the elegance and allure of a simple kiss can convey more eloquence than the speeches made by a formal council, such as the French. This emphasizes the idea that affection and beauty can have more influence than political negotiations or petitions from rulers.
In this context, the comparison between a woman's kiss and the tongues of powerful figures illustrates the theme of love's power over political matters. It suggests that genuine emotion can sway even the most steadfast hearts, using the example of Henry of England, who would be more easily convinced by a tender moment than by a declaration from kings. This connection between love and persuasion reflects a key element in Shakespeare's exploration of human relationships.
