There was no international treaty, that gave Europeans sovereignty in the Middle East. The Arab League did not intervene into any part of the Jew partition or subsequently Israel. What are you talking about. The Arab League entered the Arab and International sectors to try to prevent the Jews from evicting and killing the Christians and Muslims.
Your limited education and inability to research the source documents leaves you at a disadvantage.
Israel was attacked by Arab-Moslem armies. Your silly babbling to the contrary is nonsensical.
S/766 of 22 May 1948
What follows is one of several questions posed on behalf of the UN and the Israeli response.
(h) Have Arab forces penetrated into the territory over which you claim to have authority?
Answer to Question (h): Arab forces have penetrated into the territory of the State of Israel in certain corners of the Northern Negev and in the Jordan Valley south of Lake Tiberias. In addition, planes of the Royal Egyptian Air Force have repeatedly raided Tel Aviv and southern Jewish settlements, while Iraqi air-force planes have been raiding settlements in the Northern Jordan Valley and artillery of the Syrian and Lebanese armies have been shelling settlements in Upper Galilee from across the frontier.
