Lls Fair in Love and War referring to Shakespears Henry V

prove that alls fair in love and war using Shakespears play Henry V to support your claim. I need to point out the rhetorical devices he uses to support the claim. I need a powerful and concise thesis statement and a quote or two. It would be a plus if you could use a few of the following vocabulary words : obdurate, vicissitude, plethora, sardonic, eclectic, ephemeral, abstruse, sanguine, pernicious, fetid….just a few 2 or 3.
