So, I'm going for a peaceful cultural victory as Siam just minding my own business when I notice Montezuma massing troops at my borders. The Aztec invasion was smashed beneath my city walls and their leader sued for peace, but in 20 turns Monty just came back with a bigger army and history repeated itself. The last 3000 years have consisted of Aztec troops marching into the maws of my siege weapons, I could take over Aztec but I don't want to get too many cities because I'm going cultural, so I'm wondering if anyone has any diplomacy tricks that I can use to keep Monty from declaring war as soon as peace is made
