I suppose the corollary is that if you cannot agree on a set of ideals and rules to follow, if you are engaged with an entity that refuses to act in good faith, if you have views that are irreconcilable with your opposition, you are left in a situation where might makes right, and you damned well better be sure that it is your side that has might and that you can live with the consequences of war.
