How about letting them wipe out Israel, the ones who shall we say 'appropriated' the land from its inhabitants, crowded them into a small area.
Dont try to hand out a bunch of stuff about God giving it to them or the Balfour agreement. Stick with the core issue, the Jews stole the land and the people who lost it are rightfully pissed. You would be too if someone stole your home by hook or crook. Lay all the other issues aside and its that simple.
As much as the "Arabs" and "Palestinians" like to talk about wiping the Jews out and killing them all and such.
The FACT of the matter is they can't, they simply don't have the ability to and probably won't ever.
They also only hate Israel slightly more than they hate each other.
There is NO such thing as a "united Arab front".
The State of Israel is here to stay for good, at least until like some WWIII event wipes out most countries in the world.
At the start of the modern state of Israel the "Arabs" tried wiping out the Jews and got face stomped pretty badly.
They tried a few more times and wound up getting more curb stomped and losing more land each time.
The "Refugees" kind of came about partially because the "Arabs" told the local "Palestinians", to get out of the way so they could genocide the Jews and then the "Palestinians" could come back. Those that took up the offer became the "refugees" and those that stayed and assimilated, became the many "Arabs" that live peacefully in Israel and have posts in the government and in the military.
If the USA wasn't interfering and it came to all out war between Israel and the "Arabs", the outcome would be the Arabs getting nuked back into sand.
So sure in the end it might come to simply "let them fight" but the outcome of that fight will be Israel wins "Arabs" are mentioned in history books.
