> read it more as ‘actually holding them responsible’
What about recent events suggests Israel isn’t held, and does not hold itself, responsible for Gaza’s affairs? The principal complaint is that they’re holding themselves too responsible.
On the contrary that type of complaining and soft diplomacy does have a real effect. Israel's isolation on the world stage informs a lot of the decisions israel makes currently and has made in the past that lead to the present day.
Its not a "do this or else" sort of thing, but it definitely has had a major effect on regional politics.
Arguably one of the main causes of the current war is israel-saudi normalisation. So you could say that this yelling is so important to some factions that arab countries backing away from it triggered a major war.
