"There is that. It's been tried before and didn't work. Why did they previously repay kindness and help with mayhem and terrorism?
Until terrorists are no longer in control of Gaza there is no positive future, just more of the same. There must be some group that wants to run gaza with peace and prosperity rather than just continuing war with Israel."
Why did they repay kindness and help with mayhem and terrorism? Well largely because those that were left leaning in the West anti Israel / anti semitism in Middle Eastern countries fed the narrative of the Palestinians as victims.
Being portrayed as a "victim " rather than the "bad guys" creates a sense of resentment rather than shame and a desire for revenge rather than reconciliation.
A classic example of this is Germany - after WW1 they were increasingly seen in the West and indeed felt themselves as victims of an unfair Versailles Treaty. When Hitler came along he played this victim card and desire to get German dignity back. The West went along with this until Germany militarily conquered Poland so Poland was seen as the victim.
However after WW2 Germany was seen in the West and Russia as the aggressor who must never be allowed to be in a position of strength again. In turn
This then in turn led a feeling of guilt / shame amongst ordinary Germans rather than a feeling of being a victim and seeking revenge.
Honestly I can tell you that a lot of Jordanians want absolutely nothing to do with the Palestinians and see them as a destabilising threat to the Kingdom.
In answer to your point "There must be some group that wants to run gaza with peace and prosperity rather than just continuing war with Israel." The answer is feeling like a "hard done by victim" and asking for aid is way easier than the hard work path of reconstructing a country to become a stable prosperous nation especially as it will be a long process with a lot of economic suffering along the way.
