I think from a global general-population perspective, if things don’t go the right way there are going to be some very angry and disillusioned people. People who are already teetering on the brink of going from abject frustration to full-on rage. For one side, nothing short of a cease-fire will do (as a bare minimum); for the other side, anything imposed on them is a crime against humanity.
I feel like UN/ICJ know this, so they’ll hedge their bets and swing for the middle. No matter which way it goes, some chunk of the general population is going to be let-down. Again.
