Like most places in the middle east, peace could have already been accomplished without US interference. That’s all it takes.
However the US keeps funding and arming belligerent actors in the region, causing war after war after war since the beginning of the cold war. Without US interference, they would have fought it out and reached some sort of compromise to survive. Everything the US gets involved in is in for death and misery for decades in the region and will always end up worse than it began.
The current Israeli-Palestine situation is not a 70+ year long accidental mishap that nobody knows how to fix. It’s a cafefully orchestrated stage going according to plan. I mean they stopped Germany in the 1940s. World powers could easily stop Israel too, if they wanted. I don’t know if anyone can stop it. It seems that not even registered voters in the US can stop this.
