The Root of the Conflict.
Hint: It is not the absence of a Palestinian State
The UN once understood the 1967 Six-Day War as a war of Arab aggression against Israel. The Security Council recognized that the root of the "Arab-Israel conflict" was not where Jews lived, but that they had sovereign rights to a Jewish homeland--which the Arabs did not accept. The Arab position, in the view of the UN, was wrong--Israel had an absolute, undeniable and irrevocable right to a sovereign presence in the historic Jewish homeland.
The Security Council decided that Israel should not be forced to give back territory as it had in Sinai in 1956 without a resolution of the underlying problem. In that frame of mind, it passed Resolution 242 with its central clauses (i) and (ii):
(i) Withdrawal of Israeli armed forces from territories occupied in the recent conflict;
Not all the territories--American and British diplomats insisted then and do now--and accompanied by:
(ii) Termination of all claims or states of belligerency and respect for and acknowledgment of the sovereignty, territorial integrity and political independence of every State in the area and their right to live in peace within secure and recognized boundaries free from threats or acts of force.
All of that was to be given to Israel not by the Palestinians, who did not and do not meet the requirements of a state, but the belligerents of 1948 and 1967. Egypt and Jordan have done so. Israel is still awaiting acknowledgement of its sovereignty, territorial integrity and political independence from Syria, Iraq, Lebanon and the countries that supported the war--Algeria, Kuwait, Libya, Morocco, Pakistan, Sudan, and Tunisia. Today, Israel demands that the Palestinian Authority (PA)--successor to the PLO in the West Bank--accept those terms as well. The PA has refused.
It should have been simple. In 1967, the Arab states should have acknowledged that their obstructionism in 1948 was illegitimate and the establishment of Israel was legal and just. Some of the countries that have to make their peace with Israel will be in Bahrain, and the fundamental principle of UN Resolution 242 should be on the table.
Fifty-two years late is not too late.
