What are the causes of conflict in the Middle East?

There were some issues that led to conflict in Middle East.

Explanation:

There was religious prejudice between Arabs and Jews. There was mutual hatred, Arabs refused to distinguish Jews. Nationalism was the main reason for a feud between them.

There was a biblical Promised Land that led to a political movement, according to which Jews would establish a homeland in Palestine, which is in Middle East.

The territory that was given to Israel had religious sites for both 'Arabs and Jews'. Jews were not quite this time learning from their Holocaust experience.
