Excuse me saying this but you're expressing some pretty bleak, depressing and frankly concerning sentiments there.
To say that the opinion of the UN is irrelevant is somewhat strong. I'd be interested to know what you are basing that statements on. Did you ever have a look at the actual report from the Commission that I linked to a while back, do you disagree with their finding that Israel is committing genocide? A lot of other parties have reached the same conclusion, independent of the UN. Aid agencies, human rights organisations (including some Israeli ones), genocide scholars etc. They can't all be in bed with Hamas.
"And just to remind you, what exactly did Hamas expect Israel would do when over a thousand of their citizens were brutally slaughtered two years ago by an organisation who have the publicly stated aim of killing all Jews?"
- Who can say, but they probably didn't expect Israel to brutally slaughter >67000 Palestinian citizens. (20000 children, 1 every hour). Palestinian ≠ Hamas. Or do you contest those figures? I question the understanding of the concept of proportionality in this context. Obviously Hamas bear some responsibility here, tunnels under hospitals, human shields, etc, etc; but its naïve to believe that that is the reason we now see near total destruction of all buildings and infrastructure in Gaza.
Britain did indeed commit some horrendous deeds in WW2. As did all the other protagonists. I'm not excusing any of that, but it was all "of the time", a different era. I used to assume that we'd moved on since then. Maybe not. Irrespective of events in history, I don't see a justification for the Israeli actions. The fact that a terrorist organisation, Hamas, committed genocide on 07/10/23 doesn't make it OK for a state to then itself commit genocide in retribution, or for collective punishment, or for whatever the real reason is. Not for me anyway. It just reduces them to the base level of the terrorists.
