When a court orders you to reverse an action, it’s a recognition that you are currently engaging in that action.
So when this court ruled “that its (Israels) forces do not commit any of the act in the genocide convention.”
They are stating that Israeli forces are, in fact, committing acts covered under the genocide convention.
If they weren’t, there would be no need for the court order.
Now, Israel’s defense could be that any genocidal action is the act of individual soldiers or units and is not official Israeli policy… I don’t BUY that, but it’s plausible deniability.
In this case, now, the court is saying Israel has an obligation to stop it regardless of who ordered it.
