As well as being off topic - your assumptions (or worse) are coming through here
This is of the - when did you stop beating your wife? type question.
I could ask (on topic) - is it because Ukrainians have historically had such a brutal culture that they treat and have treated their own people is such an appalling way in Bucha and elsewhere? [for those for whom it isn't obvious, I am parroting Russian propaganda here,I don't personally for a moment believe the Ukrainians massacred themselves in Bucha]
Up until they started doing the same with Ukraine, when the people I know were pointing out that Amnesty International and the UN have in more recent times been unbelievably biased and bring out reports that bear very little resemblance to the truth - pretty much everybody rational struggled to believe it - surely these are organisations dedicated to justice and truth, they couldn't possibly the the dupes (or worse) of propaganda?
But I am afraid while "first they come for the Jews", it never stops there. Then they start coming for others. The reason Russia genuinely has scope to convince people that Ukrainians are Nazis and are doing all these terrible things, is because the ground was already laid by the propaganda of organisations like Hamas (aided and abetted by the same Russian bots who are churning out Ukrainian propaganda now was well)_. Once you start believing all the propaganda that Hamas produces, you are well on the way to believing everything about Ukraine that Russia churns out. And, of course, lies go all the way around the world before truth has time to put its boots on, because proving the truth is hard. Even in cases where it there are videos of rockets firing and trajectories and such. Many people simply refuse to believe it.
Fighting wars, unfortunately, tend to involve civilian casualties - the Israeli army goes to unbelievable lengths to try and minimise them. That is the fact. Not because of what the world says, because the world will insist they drink the blood of children whatever they do, but because of their own, internally driven, moral sense. But if you insist on believing the lies there is nothing one can do, any more that if one insists on believing the lies the Russians are churning out about Ukraine there is simply nothing one can do. Because fighting an avalanche of well financed lies addressed at those who want to hear them is near impossible. Just as Ukraine probably would avoid more civilian casualties by not fighting - despite the odd massacre here and there (they could have rolled over and accepted the invasion when the Russians came in for a start), so too Israel could. But any decent, moral person, with the capacity to see through propaganda, should be able to understand that ultimately evil has to be fought. But unfortunately unless you are very close to the reality, it can be very hard to see through the propaganda.
Our only hope paradoxically is that, eventually, enough people will be subject to the same treatment, that they will start to realise the nature of the scam, and as a consequence we will find some effective way of combating the propaganda. But at this point , I don't know how to achieve that. We are still, only just at the first they came for the Jews, and second they came for the Ukrainians stage in the propaganda stakes. Whatever turns out to be most effective, propaganda wise, about the middle east will be applied in relatively short order to the war in Ukraine. That much I can virtually guarantee.
