Was Shakespeare's Troilus and Cressida pro or anti-war? What are some quotes, and solid reasons to back up each case?

Shakespeare's intention, perhaps, is not to present a pessimistic world both inside and outside the walls of Ilium in order to induce a similar pessimism and cynicism in his contemporary audiences; rather, he reduces the mythological figures of the antique world to human proportions in order to debunk the notion that the antique world embodied a nobility and virtue against which the Elizabethan world could not compare. It is worth noting that the practice of idealizing the past is not limited to the Elizabethan's idealization of antiquity. Many societies look back on past times and wistfully recall values that the present time may lack.
