With this .per, computer players will not change diplomacy when they are attacked by human players and will continue to fight the enemies. Useful for a scenario where a computer player MUST stay allied with the human player.

This is probalby one of the most useful AIs in the granary, without this having the player liberate a city without the citizens trying to stop him would be hard. :P Although little has been changed so making a more custom AI would be pretty easy, but if you don't have time to learn about designing AI's this is perfect.
