If my understanding is correct the jews were kicked out a long time ago from the middle east by the Romans. They found new homes in Europe.
After WW2 the jews were again kicked but this time by the europeans. So they returned to the middle east which was then the home of the Palestinians. So a war was started that was never resolved to this day. The Israels have the upper because of the support of the US but what is going to happen with the decline of the US?
