The rest of the world haven't been shy lately about expressing their opinion of the war, something that Israel recognises and care about, but they have provided no way out for israel to take any other course of action.
Our ideas and opinions should be as harmonious as possible with reality. If Israel was understood better and her concerns and fears engaged seriously it would go a long way to ending the war.
In the context of this assassination i feel the path forward is not empty platitudes of "deescalation" rather greater empathy and understanding of people you disagree with. This is mainly an internal process, but also one that should have outward expressions too.
