The root cause of the Israel-Palestine war is a complex issue with many factors that have contributed to the ongoing conflict. The following are some of the key factors that have contributed to the conflict:

• Zionism and Arab nationalism: The roots of the conflict can be traced back to the late 19th century, with the rise of national movements, including Zionism and Arab nationalism.

• Displacement of Palestinians: The establishment of Israel, and the war that followed and preceded it, led to the displacement of hundreds of thousands of Palestinians who became refugees, sparking a decades-long conflict between Israel and the Palestinian people.

• Occupation and treatment of Palestinians: Those more sympathetic to the Palestinian cause see the tragedy as the inevitable result of decades of occupation and Israel’s harsh and prolonged treatment of its Palestinian subjects.

• International involvement: The United Nations’ vote in 1947 to partition land in the British mandate of Palestine into two states – one Jewish, one Arab – following the destruction of much of European Jewry in the Holocaust, was a starting point for many people.

• Tensions between Jews and Arabs: Tensions between Jews and Arabs grew when the international community gave Britain the task of establishing a "national home" in Palestine for Jewish people. For Jews, it was their ancestral home, but Palestinian Arabs also claimed the land and opposed the move.

• Wars and fighting: Because there was never a peace agreement - with each side blaming the other - there were more wars and fighting in the following decades.

It is important to note that the conflict is a complex issue with many factors that have contributed to it. The above factors are just some of the key factors that have contributed to the ongoing conflict.
