This is not a problem that has a money solution. At least not at this point. One big misunderstanding of the "west" is that everyone wants the things that "they" do. Like a nice car, house, money, Costco, Walmart. Doesn't work like that.
Oddly enough the Palestinian Authority is siding with Israel in that Hamas can not control Gaza after the war. They just made a statement to that effect. The PA depends on Israel, Israel supports the PA, the Palestinians don't always like the PA. The PA is arguably happy with the IDF going after Hamas and PIJ in the West Bank in places like Jenin ( https://en.wikipedia.org/wiki/Jenin_Brigades ) because Hamas wants to overthrow the PA just like it did in Gaza. The Israeli government makes a bit of a show of being against the PA while actually knowing very well it needs the PA and collaborating with the PA on security. OTOH the current government does not want the PA to get control of Gaza.
The "west bank" problem right now is that the extremists amongst the west bank settlers have more or less free reign by the government to attack Palestinians (and sometimes other Israelis). This is a result of Netanyahu's brittle coalition and the war. The Israeli right wing has always wanted to make sure there can not be a two state solution. What they still haven't quite wrapped their heads around is that they will instead have a one state solution. Really that would appear to be the only solution of sorts. Oddly enough the international community is still stuck in this "two state solution" despite it being completely unacceptable to both sides in this conflict and having proven to not work.
