Why are Israel and Palestine always in a state of crossfire?

Simply put, it is religious reasons. Palestinians believe in Islam, Israelis believe in Christianity, and Germans slaughtered Jews in World War II. After the end of World War II, the Jews described in the Bible should now be Jewish territory, so there is an irreconcilable contradiction between the two sides because the Jews want to establish a state in Palestine. Jews are smart, so they have money. Many rich people in the United States are Jews, so the United States supports Israel and supports Israel. Because of the growing support of the United States, the war between Palestine and Israel is becoming more and more serious.
