Why is there ongoing conflict between Israel and the Arab-Muslim world?

Jews fleeing persecution in Europe wanted to establish a national homeland in what was then an Arab - and Muslim-majority territory in the Ottoman and later British Empire. The Arabs resisted, seeing the land as rightfully theirs. An early United Nations plan to give each group part of the land failed, and Israel and the surrounding Arab nations fought several wars over the territory. Today's lines largely reflect the outcomes of two of these wars, one waged in 1948 and another in 1967.
