First and before all, Rothschild are not German, they are Jews, being Jewish is not only a religion like in Christianity or Islam, being Jewish is a religious and a national identity, with a Land, Israel, given by God. Jews can be born in Germany, speaking the German, wearing a German name, they will never be German, they are Jews, they are Israeli, Jewish is the religious part, Israeli is the national part, but it's linked.

Israel is a people, but they have a Land, given by God in the Bible, and it was given far before Jesus, it started with Abraham. Jews occupied the Land many times, they where exiled many times but they have ever returned to their Land. This is history, you can't deny the past, check the Arch of Titus for example, there is a Menorah, it's a Jewish religious symbol, there is ancient Roman Empire coinage which celebrate the destruction of the Jewish Temple, in Jerusalem, all of this is around 70 after JC, far before 1948... but there is absolutely no trace of any "Palestinian people" before something like 1960, the Palestinian people was a creation of multiple Arabs countries, including Egypt and Jordan. They where Arabs in Israel before, yes, but they never claimed to be the "Palestinian people", before when we talked about Palestinians, it was about Jews, it was an insult
