Richard,

If the treaties ending WW I and the countries created are not valid, I think that you should look at how many nations you have just made illegal- Lebanon, Jordan (twice over!), Syria,Iraq,Much of eastern europe,etc.

If you insist that ONLY Israel is illegal, while the others are OK, then you fall under the EU definition of an Anti-Semite.

Mandate Palestine was as legal ( and not more so) as Lebanon, Syria, and Iraq)

"The decisions of the San Remo conference confirmed the mandate allocations of the First Conference of London (February 1920). The San Remo Resolution adopted on 25 April 1920 incorporated the Balfour Declaration of 1917. It and Article 22 of the Covenant of the League of Nations were the basic documents upon which the British Mandate for Palestine was constructed. Under the Balfour Declaration, the British government had undertaken to favour the establishment of a Jewish national home in Palestine without prejudice to the civil and religious rights of existing non-Jewish communities in Palestine or the rights and political status enjoyed by Jews in any other country. Britain received the mandate for Palestine and Iraq; France gained control of Syria, including present-day Lebanon. Under the agreement, Great Britain granted France 25 percent of the oil production from Mosul and France undertook to deliver oil to the Mediterranean. The draft peace agreement with Turkey signed at the conference became the basis for the 1920 Treaty of Sèvres. Germany was called upon to carry out its military and reparation obligations under the Versailles Treaty, and a resolution was adopted in favor of restoring trade with Russia.[12]

Recognizing that not all parts of the Middle East were ready for full independence, mandates were established for the government of three territories: Syria and Lebanon, Mesopotamia (Iraq) and Palestine. In each case, one of the Allied Powers was assigned to implement the mandate until the territories in question could "stand alone.""
