Sure. The majority of my plan is already laid out in a resolution before the UN.
Israel should respect the internationally recognised 1967 borders and stop encroaching beyond them (including, for example, the parts of the West Bank Barrier that cut in to Palestinian territory).
It should immediately stop the activities of the settlers stealing land and terrorising innocent people in the West Bank. It should also dismantle the existing settlements and rehouse the existing settlers within Israel's borders.
It should, obviously, end the blockade of Gaza and the occupation of the West Bank. But equally obviously, this would bring security concerns. I think if Israel agreed to the first two and conditionally to this one, the Palestinians should demilitarise completely, subject to a strict non-aggression agreement with and from Israel, enforced by UN peacekeeping forces who would remain in Palestine. Aid for rebuilding would be conditional on their cooperation.
Again, most of this plan already has near-universal support from the international community. The only major holdouts are Canada, the US, and, you guessed it, Israel.
It's been voted on several times over the past 20 years or so, always with almost unanimous agreement. In the last vote, in 2022, 153 UN member states voted in favour of it. Including Palestine.
I'll also add one final specific point, which is that I think the Israelis should abandon this insistence on a Jewish majority in Israel in favour of a single, truly democratic state where everybody has equal rights. I don't expect them to do this, of course, but I don't see anyway to maintain their ethnocracy without some version of the racism and violence we're currently seeing.
The Jewish population will grow, either through Aliyah or reproduction, and even if they stay within their borders, they will eventually outgrow Israel. This, I believe, is the reason why Israel has never reigned in the settlers.
And given that there is also an Arab population in Israel, who are also reproducing, there will always be the worry of an Arab majority threatening Jewish supremacy. Several Israeli leaders have spoken about his problem. I don't see any solution other than a truly democratic state.
Again, I don't think they'd ever do this, nor do I think the US would allow them to, and yes, I also understand the security concerns this would cause. This is just my kumbaya, pie in the sky, addition to the list.
