I learned on this platform today that you are not allowed to say it’s a war crime until the ICC says it’s a war crime. So you could just get away with war crimes if you don’t sign the Rome Statute and don’t let ICC investigators into Gaza*.
Hypothetically speaking of course.
*) interestingly enough the Palestinian State, although not universally recognized, is a signatory. Technically the ICC has jurisdiction since they claim Gaza as part of their territory. It’s going to be interesting to see how that is going to unfold.
