When this Gaza conflict started, I saw how the Israeli protested against their government and demanded peace, so I thought there is a semblance of an excuse for glimpses of abhorrence being reported - "it's a small number of people in power, not the Israeli nation doing it, and also there are always 2 sides to the story".
Since then, there have been unfathomable horrors and crimes against humanity done from the Israel side, with extreme intensity and one-sidedness, and it's now been going for so long. I can find no excuse of any kind anymore, for what has been and is being done in Gaza. I don't think any normal person could. The weight of these things, in my mind at least, is such that if the Israeli people really wanted anything different, it was their human duty and utmost responsibility to stop this by now, in whatever way needed. They didn't... It's sad that people who have suffered so much as well, let themselves become the villains to this depth and extent.
As horrible as the Israeli mindset is, their subjective viewpoint is at least somewhat relatable: An ordinary Israeli citizen is born in that land, knows nothing else, just learns that the entirety of the surrounding populations want them dead - and will with very high likelihood experience terror attacks themselves. That this upbringing doesn't exactly make you want to engage with the other side is psychologically understandable.
(I'm imaging this as the universal experience of all Jewish Israelis, religious or secular, left or right. I'm excluding the religious and Zionist-ideological angles here, because those are a whole different matter once again)
What I absolutely cannot understand is the behavior of our states. We're pretending to be neutral mediators who want nothing more than to end the conflict, yet in reality, we're doing everything to keep the conflict going. We're fully subscribed to Zionist narrative of an exclusive Israeli right to the land (the justifications ranging from ostensibly antifascist to openly religious) and we're even throwing our own values about universal human rights and national sovereignty under the bus to follow the narrative.
If the messianic and dehumanizing tendencies of Israelis are answered by nothing else than full support and encouragement of their allies, I don't find it exactly surprising that they will grow.
Or is it the leader class in most western countries have no sense of duty , are effectively cowards, and are in it just to have a profitable, white-collar career ?
They are cowards who are just in it to enrich themselves by bribery, theft, and extortion.
You are looking in the right direction and not seeing just how far our society has gone.
