If neither side can agree on peace, if neither side has objectives which the other will accept, if neither side is willing to compromise; What other outcome is possible in terms of realpolitik?
It is upsetting to observe. We all want better for humanity.
Of course it is understandable to be outraged by the violence and atrocities. The human suffering is real, but arguments focusing on these points can miss the larger picture. The underlying incentives dictate outcomes. Atrocities are often marketed as rationalizations for further violence.
We want to prescribe an outcome without atrocities. Yet discussions fall into recrimination before they can describe the conflict coherently.
