At this point I'm not even sure there is peaceful solution anymore, because that would require everyone to act like adults and stop killing each other; but apparently they cannot do that, and haven't been able to do that for... well... ever. So what do you do when children cannot play nicely and share their toys? you take them away.
How the fuck do you take away their toys without telling everyone to get out (Israel, Palestine, etc.) and having all the nuclear powers (excepting Israel) glass the entire region making it uninhabitable for the next 20,000 years?
