My position is simply this. Israel are of course justified in responding following the outrages of 07/10. nutralising active terrorists still inside Israel, going after those who committed, sanctioned and directed such attrocities using leathful force. And later, taking steps to ensure future security.
But in the process so far, killing thousands of Palestinian civilians, destroying or at best severely compromising life support infrastructure and services they rely on, enacting collective punishment etc, is not justified. If the Israelly leadership's idea is to solve their security problem by largely depopulating Gaza, with the horror that implies, how does that even work in the medium to long term anyway.
