ICJ orders Israel to prevent genocide in Gaza, stops short of ordering ceasefire

What's the ICJ's actual ability to enforce this? "Orders" sounds like they have some sort of weight to throw around if Israel doesn't comply, but I'm not familiar with the ICJ or what possible consequences could arise if Israel simply decided it was going to do what it wanted.

Zero, the same as most courts.

Enforcement is a matter for (ordinarily) the Security Council, or, in the case of deadlock, potentially the GA acting under Uniting for Peace. Well, decisions on enforcement; actual enforcement is left to individual UN members, acting on direction of those UN bodies.

Note that enforcement in practice is often a problem, as with the provisional measures adopted against Russia in the Ukraine v. Russia genocide case.
