The correct answer is C) both sides view each other as enemies.
The Arab-Israeli conflict refers to the political tension and armed conflicts between the State of Israel and its Arab neighbors, especially the Palestinians.
This conflict is rooted in the matter of the sovereignty over the historical land of two peoples: Israel and Palestine. It can be traced back to the end of the 19th century with the rise of Zionism and Arab nationalism. Other Arab neighbors saw the establishment of the State of Israel after the WWII as an occupation of Arab land, and therefore, an insult and betrayal to all Arabs.
It also has an important religious component, since Jerusalem is a sacred city for Jews and Muslims, and many Muslims see the Israeli rule over Jerusalem as an occupation over Islamic territory. For all these reasons, Arabs and Israelis view each other as irreconcilable natural enemies.
