"Prosecutor’s rush to seek these arrest warrants" does not seem to be true.
ICC prosecutor did not bring this case quickly without warning. He has consistently demanded that action must be taken or he will prosecute. Israel's Supreme Court has the authority to conduct judicial review of laws and government decisions and intervene in exceptional, extreme cases. Israeli prosecutors have had time to charge.
>Since last year, in Ramallah, in Cairo, in Israel and in Rafah, I have consistently emphasised that international humanitarian law demands that Israel take urgent action to immediately allow access to humanitarian aid in Gaza at scale. I specifically underlined that starvation as a method of war and the denial of humanitarian relief constitute Rome Statute offences. I could not have been clearer.
>As I also repeatedly underlined in my public statements, those who do not comply with the law should not complain later when my Office takes action. That day has come.
