This is why the hardliners and extremists of both sides need to be eliminated, because they are the enemies of everyone else, not each other. Those extremists never really attack each other, because the deaths of the civilians they are supposedly associated with is their real goal. That terror gives them more power.
If however these extremists were to cease to exist, the rest of the people would be much more willing to actually work with each other to improve everyone's situation. Right now, they're stopped from helping the civilians of the Gaza Strip who suffer from this devastation, because their suffering serves both the Israeli hardliners who want to create a mass "leeches" who would destroy the paradise they claim they've created, as well as the Palestinian hardliners who use the suffering of these people to get the sympathy of the world . . . and financial support from those sympathetic viewers of their situation. All those extremists live the high life of the tension they've created while never having to deal with the tension itself.
Basically, the hardliners of both sides are terrorists, the general public of both sides are the victims caught between two groups of psychopaths.
