what should you do? It often happens that your neighbour DoWs you with a DoF active. After beating back this assault and securing a peace deal, how do you proceed towards them? 1) befriend them again. They are now quite likely desperate for trade partners, and no-one trusts them anymore. If they backstab again, that just puts them in a deeper hole. 2) Denounce. They have the "backstab" negative diplo modifier and after the conflict ends, their army is probably weaker than the other civs. Likely to result in a chain of denouncements. 3) I avoid denouncing them because i never accept peace. Reduce them to one city and no army then pay their neighbours to DoW them and let their neighbour capture their last city. Similarly, how do you act towards neighbours that DoW you (no DoF active) once peace breaks out? Bury the hatchet, denounce or kill? I usually go with option 1), unless they're someone like Shaka in which case i need to protect my future security by weakening them a bit, at minimum. Capture one of his border cities to use as a buffer zone, citadel bomb his great person improvements, capture his workers. Yesterday though i got backstabbed by Elizabeth, i had all my trade routes going to her and lost the lot, i had done NOTHING to antagonise and her closest city was 12 tiles from one of mine. She just did it because she perceived me the weakest, with only 1 xbow and 1 longswordsman in each of my cities (hilly terrain). Denounced her, she was hostile for the next 500 years.
