If the ICJ verdicts against Israel, the blood of every Israeli and Jew that Hamas murders thereafter will be on the hands of South Africa as a country, as well as all who approved of the action against Israel.
I believe Hamas idea is the genocide of every Jew in Israel. Their Iranian backers have a very poor record on human rights and also back Hezbollah, who have turned Lebanon into an armed camp, and the Houthis, who are active pirates who have attacked British and US warships. Nobody with any conscience can support Hamas after their atrocities that started this particular war. Let's hope Israel can finish this war quickly, for everybody's sake.
