Maybe trauma you are talking about it's just excuse to control opinion of voters and manufacture consent but under the hood its just all about power and being rich (not always but in many cases).
Take the Greeks (that's my people! Us!) and the Turkish. I guess people in the West don't remember this but the Israelis are not the only people in the Middle East who have a word that means "disaster" (Shoah, for the Israelis; Καταστροφή- Catastrophe for us), that when anyone says it everyone knows exactly which disaster is spoken of. They are not the only people who lost the land their ancestors inhabited for thousands of years (Ionia, for us Greeks), who lost their greatest city (Constantinople, the City), who lost their greatest temple that was turned into a Mosque (the Hagia Sophia). Us, Greeks, too, have suffered these ignominies at the hand of the Turkish. Our common history with the Turkish is one of war, destruction, violence and blood. So much blood.
Genocide? https://en.wikipedia.org/wiki/Greek_genocide Check. Ethnic cleansing? Check. Death marches through the deserts? Check, check, check.
And yet, since the Catastrophe, in 1922, we have been at peace with the Turkish, even through serious hot episodes in the Mediterrannean, like Cyprus. That's 100 years of peace, after 1500 years of history of war.
It can be done. The trauma can be overcome, if both sides agree to it. To quote none other than Moshe Dayan: if you want to make peace you talk to your enemies, not your friends.
It is a lot easier to conclude peace if both adversaries have a plenty of "their own" land to live on and can sorta-kinda ignore each other while doing so.
I don't see this any different to terrorism apologia (the trauma of 1mn dead in Iraq and another million in Afghanistan, for example). I guess, if the leaders wear suits & ties and hide behind the garb of democracy, then we should all understand why military they command commit crimes against humanity.
Every perpetrator of terrorism sees himself as a victim. Such is the case not only with individual terrorists, who often compete with their enemies over who is more victimized, but also with terrorist groups and nation states.
The problem isn't the "trauma". The problem is the excuse.
> they are as well unable to recognize how scarred and traumatized is Israeli society from centuries of events
First, 400mn Arabs (or 2bn+ muslims) aren't a monolith or brainless zombies. Second, the "centuries of events" is just European guilt. Nothing to do with the Arab world.
> So, without a generation of leaders able to recognize and understand the role of history and those traumas and empathize with the other sides we're trapped in those loops of aggression.
The sad reality (imo) about this truth is that the qualities needed to be a leader aren't empathy. There was a vid about it which went more into detail but When you observe leaders, you find that they are extremely weird and sometimes psychopathic.
To me it also feels like if a leader is emphatetic towards the other part, other leaders more extreme would spring up saying that he's an enemy from within or something equivalent to it.
The empathy of the leader is one of the most disregarded qualities. I would go so far as to say that leaders aren't even empathetic towards the general population of their own nations/community sometimes.
It's really sad but the Empathy you mention and cowardice can look the same to many & the Empathatic leader would get booted out of/not given a chance.
For example, within America itself, I feel like John mccain was a good guy and I would consider him empathetic in the sense that I remember seeing interviews of him saying that he and Obama just have some minor differences in policy making when there were people attending his rallies asking that they don't feel safe about Obama.
I am just gonna say that This leader of republican party was lost for what is now Donald Trump.
Oh I just watched the rally/interview again[0], when he said that you don't have to be scared of Obama, he was audibly booed by the public. (But also they clapped once when he said later in the campaign that Obama was decent person?)
It isn't impossible to have empathetic leaders but I do think that perhaps as a civilization, we would need to take class act/honesty/integrity more into account than we take in the current system which to me all across the world sometimes feel like picking the lesser evil/not-greater-good at times though I can only speak for myself.
The only traumas maybe related to money is ... Great Depression but it's not like somebody else was responsible for that
