It doesn't matter what the IDF or Netanyahu say at this point; this is entirely indefensible and there is no explanation behind this attack besides cruelty and intentional mass murder.
I hope that everyone involved in dropping those missiles suffers a guilty conscience for the rest of their days, but I know that it probably won't bother them at all.
The bombing "double tap" is often used to try to maximize damage to first responders, and hurt morale. The first explosion goes off, attracts first responders, police, medical care etc, second explosion goes off to inflict maximum damage on the targets ability to respond in the future.
Secondary effects: future responses will be delayed due to fear of double tap attacks.
It's so frustrating that everyone's still tiptoeing around language for Israel.
Is it a war crime or not? There's no room for 'may be'. There are very clear guidelines that say that it is, quite definitely a war crime, and dancing around the subject is preventing international bodies from Outright condemning it and revoking support.
Bombing a refugee camp is an evil, despicable act. Israel has crossed the line several times but the US and UK are too cowardly to restrain this racist, psychotic ethnostate.
