The stories of our forefathers describe a world where conflicts can be generally resolved either by violence, deceit, accident or some heavenly intervention but not through a civilized negotiation and peaceful agreement (probably besides rebuking the shepherds for the wells).
The story of Yitzhok's blessings is not different. I have to tell I didn't see it coming, nothing in the Torah seemingly required that Rivka turns on her husband, Yaakov disobeys and deceits his father etc. I think it would be OK if G-d tells Yitzhak to listen to Rivka just like He told Avraham to listen to Sarah, and they would sit together around the table and split the Blessings in a way that would please everyone.
The bonus part - there would not be any hatred and probably many catastrophes would be spared.
So could that crisis be resolved in a way of דרכי נעם and if not - why?
