"The Children of Israel" is an old expression from the Old Testament. Back then it simply meant: "those people belonging to the 12 Tribes of Israel and worshipping Jehovah". Israel was a mental/spiritual concept, not a physical place.
It is incorrect to associate the mental/spiritual concept with a physical place located in modern Palestine. The concept was around for thousands of years, the state of Israel was created as a physical/political extension of that concept in 1948.
Hitler had plans to do similar things in western Russia, on a bigger scale of course. He also had a spiritual/mental concept of a chosen people, a Master Race as he put it, and that was the Germans(Aryans according to him). They also were seen (by him) as God's chosen people. They needed "lebensraum" (living room)...according to him...and that room was going to be found in the vast plains of western Russia, rich in grain. By displacing the existing Slavic populations, Hitler was going to provide the German people with the room needed to achieve their god-given destiny. This would, of course, be at the expence of the local inhabitants! They would have to be removed somehow. Guess how? By war, that's how.
Any of that sound familiar?
Well, Hitler tried it, and the local people resisted. My goodness, how they resisted! They must not have believed that the Germans were "the chosen people". ;-)
It's always hard to convince an invaded people that they are less entitled to their own land than you are...for some reason...
Hmmm.
The indigenous Jews in Palestine (sephardic Jews) and the local Muslims had been getting along fine with each other in Palestine for a very long time before European Jews arrived in the late 40's, unilaterally declared the existence of a brand new political state on other people's land, and used violence to achieve it.
Now, however, we have the existence of that state established in no uncertain terms, and that is clear. So what must be done is to assure its future security from being attacked...and also assure that it returns areas outside its pre-1967 borders and does not attack its neighbours or annex their land.
In other words, BOTH sides have to be convinced to stop attacking each other! This cannot be achieved when the great powers refuse to act as honest brokers and when they blatantly favor one party over another. The USA, for its own strategic reasons has blatantly favored Israel. The Soviets, for their own strategic reasons, blatantly favored Israel's enemies. Great power politics have contributed to a great many deaths in the Middle East, because the great powers have not sought real peace, they have sought strategic advantage. They only want peace insofar as their own immediate security is not threatened in too dire a manner...and insofar as it allows them to continue accessing all the oil they require.
This isn't about anything nice, like freedom or God or democracy. It's about dominance and survival.
