I think its likely israel will comply. The order is pretty weak and mostly stuff israel already claims to be doing. It wouldn't be worth the PR hassle to ignore it.
Comply with "Don't genocide"? At best, they'll argue semantics while they keep doing what they've always done.
Nevermind. I read the article:
> Israeli Prime Minister Benjamin Netanyahu said the fact that the court was willing to discuss the genocide charges was a “mark of shame that will not be erased for generations.” He vowed to press ahead with the war.
Its also not like this is a totally unreasonable conclusion either. Lots of international law scholars think israel is likely to win the case overall unless some bombshell happens.
