Answer:
The correct answer is: between Israel and the Palestinians.
In response to the growing anti-Semitism against Jews in Europe, a Zionist movement emerged in the late nineteenth century, which defended the establishment of Jews in Israel. Many Jews emigrated to Israel after World War I, but at the end of World War II and the shock caused by the Holocaust the partition of what had been the British mandate in Palestine in two was approved: the Jewish part and the part Arab. The Arabs did not accept it, and in 1948 declared war on the newly created state of Israel, but were defeated by the Israelis.
The keys to the issues of this conflict are: mutual recognition, the establishment of secure borders, water rights, the murders of Palestinian civilians, Palestinian terrorism, control of Jerusalem, Israeli settlements , the freedom of the Palestinian movement and the legality of refugees.
Within the Israeli and Palestinian societies, the conflict generates a wide variety of views and opinions. This highlights the deep divisions that exist not only between Israelis and Palestinians, but also within each society. A hallmark of the conflict has been the level of violence that witnessed almost its entire duration.
