It's the law of complicity that comes into effect rather than just the principals named like Netanyahu. If you were complicit then you can be charged for complicity in war crimes. That's why only a handful of nazis were executed as principals and many thousands more were executed for complicity in war crimes.

This means it is much broader than Netanyahu but those that support the actions of war crimes can be arrested. Potentially quite a few supporters of the Israeli action.

Here it gets interesting.
