How did Lord Balfour influence the Middle East Crisis?

Answer 1

Lord Balfour created the official British Policy that the Kingdom would look favorably upon the creation of a Jewish State in the Mandate of Palestine. This policy called the "Balfour Declaration of 1917" galvanized the Zionists and was their first real political success at Jewish foreign relations. The Balfour Declaration eventually led to UN Resolution 181 which gave the Jewish State the Right to Declare a State. The Establishment of the State of Israel and the Arab Response to such an Establishment is responsible for much of the Middle East Crisis as concerns Israel and Palestine.

It is important to note that there are many other Middle Eastern Crises (such as the American Invasion of Iraq, the Syrian Occupation of Lebanon, the Bahraini King's crushing of internal opposition, and the Moroccan-Algerian Sands War to name a few) which are entirely unrelated to both Lord Balfour and Israel/Palestine.
