I think Jews and Palestinians both need a place where they can feel safe from anyone trying to kill them off since it's something one group has already been through and the other group is going through right now and both are at risk from it happening again in the future. This means they either need to give one group a new homeland, which, at this point, would be ethnic cleansing of either group, or find a way for them to share one homeland safely. No ethnic cleansing should be allowed and future ethnic cleansing should be prevented to the best of the international community's ability.

Personally, I would prefer UN administration of the region until something equitable for both Jews and Palestinians can be resolved.
