I'll preface that my knowledge of the situation is 'bad'. In that, I think I'm likely not qualified to give informed opinions on it. Okay, that out of the way...
> Ideally? Palestinian accepting the existence of Israel, foregoing their demands for the right to return and East Jerusalem, and then we can peacefully coexist.
Right to return is a tricky one here. It's been very long that they have been 'out' of their homes/locations. So much so that it's difficult to say whose it is now. Which, yeah, that's not good. I come at this from a Native American perspective. In that, my ancestors took land away and had land taken away from them. I can feel that pain still in the family and that listlessness and hurt in me to a (absurdly) small degree.
From what I know, the sticking point of all sticking points is the Temple Mount. Each side wants it to the exclusion of the other. And from what I can see, each side is willing to mortgage their children's and grandchildren's lives on that point. Literally, this is the hill they are willing to die on, and sacrifice their progeny on too, endlessly (ancient allusions come flying out here without much effort).
I used to think that someone could 'Kind David' that land and just nuke it or something. But no, they would fight over the glowing green hole too, like the irradiated wasteland in Fallout 4. To an outsider, it's hopeless, I don't think that either side is willing to ever peacefully relent on the Temple Mount, let alone all the other land.
> Realistically? Maintaining strong border security, erect more walls, prevent Palestinians from crossing into Israel, legally or illegally, control any gate they have with the outside to prevent smuggling of weapons.
I don't see how treating the Palestinians poorly is going to make things better. Their incentives are badly aligned with Israel's if they are treated in such a way. I don't think that trying to forcibly make them a separate entity is going to get them to do what Israel needs. To me, the best way to get Palestinians to stop the violence is to have them 'grow' their way out of it. In that, they are so busy thriving that they no longer care about the past issues. This, I admit, is a very American perspective, and a western American one at that. I know that my idea here is a longer term one, and right now the short term is very critical. But, for me, it's a matter of incentives. If Israel can somehow make it so that the conditions exist that Palestine is more interested in something other than the destruction of Israel, then all the better. I have no feasible way to accomplish this though. I can only say to look at places and times where such things did occur. My terribly brief survey of this says that it's a matter of poverty and growing out of the 'hole' was the solution when it did occur. Still, I know that the deep and long hatreds overshadow it all.
My solution is a glib one. The participants just need to stop being who they are. These ways don't seem to work well. My automatic reaction is that they all just need to do the hard work of true forgiveness. But, again, that's not who the participants are. That is a Christian method for Muslims and Jews; it's not going to happen.
I guess my main disagreement is that the proposed solutions don't deal with the longer term, just the shorter one, and they don't accept the agency and feelings of the Palestinians and their incentives.
Thank you for the opportunity to discuss and learn more. Please tell me where I am wrong and missing out on things. Also, sorry for delays in response and I think we're in quite different time zones and schedules.
