Obviously an immediate and permanent ceasefire. israel and the USA pay for all of the damages they caused, plus other punishments (having to pay money or facing sanctions, not like, collective civilian punishments). Israeli military is tried and punished for war crimes, civilians blocking aid receive some sort of repercussions too. Palestine is given total sovereignty and independence, from Israel. Preferably they’d get back a significant portion of their original land (from the early 1900s), but how much would be outside of what I can reasonably say, possibly all of it though.

If you’re asking what I think we should actually do right now? I’m no politician but I’d say that not shooting and bombing people is a pretty quick and simple thing to do if you’re (politicians) not a psychopath.
