There is a real risk they may be found guilty of genocide ( they have done it, they are guilty etc.. no doubt about that ) but the political space to stop that ruling is decreasing. This ruling will allow the global south to apply sanctions on israel, both import and export based. BDS movement will have more weight behind it.. The global south wants to make an example out of Israel and, now, they have the means to do so. they are tired of getting beat around by the west who have weaponised these global structures for their own political and strategic ends, and now the global south have found a way of revenge ...
Even the west is saying, "they have the right to defend, but it has to be legal etc .." .. the writing is on the wall for israel. Guilty ...
What is required is a ceasefire now so that the bloodshed can stop.. and then the law of the law must take its course.
The only thing that may stop this trail is pressure on south africa from the USA/UK/EU, but if they try, it will be an interesting one for them to try.
