It's 100% true that people hold Israel to an entirely different standard than other countries because of the obvious reason.
It's also 100% true that (if in the UK - or indeed in the USA), we are living in a Christian country and there are many other countries who also have a religious basis so Israel is also not unique in that respect. It's just unique regarding which religion is at its centre.
Hamas was originally elected, and then took over Gaza very quickly. Their ethos is all about destruction of Israel (and disdain for women) and they absolutely did cross the border to attack, rape and murder on the 7th October. If you think about how many people they murdered as a proportion of the population of Israel, (roughly 10 million people in Israel compared with roughly 70 million in the UK), it would be like if France showed up in southern England and murdered 7,500 people and kidnapped another 1700 (very, very rough calculations). What would the UK do next?
The entire thing - from 2000 years ago to today is heartbreaking but obviously we can't fix any of the past. I have yet to see any sort of answer about where to go from here. No country could ever allow that sort of thing to happen without responding, Hamas is a reign of terror for everyone around them, there's no 2-state solution that either side can live with as there is 0 trust at all, and at the core of it, is an entire generation of people (on both sides) growing up in this terrible time and bringing this into the next 50 years.
I am sure there must be something to suggest - it's mind blowing when you think about how we holiday in Germany and Japan today. That would have been impossible to imagine at one point and now here we are. So it must be possible. I just can't see it at all just now.
