Israel has been the Jewish homeland for THOUSANDS of years.
Them going back to it is completely reasonable.
Your knowledge of history is lacking.
In 1880 Jews made up 4% of Palestine.
Hebrew was a dead language. It was not spoken by one native speaker on the face of the earth.
Palestine had not been majority Jewish for 2000 years before Zionism started.
What you are suggesting is that in 2000 years from now, in the year of our Lord 4024 my decedents could say: “You know what...WE are Irish. We deserve Ireland. We should go there and take it back over from the african and muslims who have moved in and controlled it for 2000 years. That is ridiculous. I think the white Irish should do something to stop it now but in 2000 years from now, it will be too late. Any attempt to take it back will rightfully be considered an invasion.
I suggest you learn a little more about the history of Zionism, Israel and Palestine and how we got to where we are.
