Peace Interest is a temporal diplomatic variable. Its purpose is to emulate how willing a wizard is to make peace with another. As such, it serves no functions whatsoever unless there is an ongoing War. Changes that happen prior to the start of the War are irrelevant, as the start of the War automatically sets the variable to a fixed value. Peace Interest is not symmetric. In relations between the human and AI players, only one side of the variable pair is being actively used, but in AI to AI relations, either side can be used depending on which AI player is offering the peace to the other.
