There have been many British decisions in politics, both local and global, which have been of dubious benefit to both Britain and the wider world: but the one outstanding piece of diplomatic British expression was the Balfour Declaration of 1917, which could be said to have been the stepping stone for the creation of modern Israel, with its Independence on the 14th May 1948.
The State of Israel, the ONLY Democratic State in a veritable sea of Arab dictatorships, has persevered, despite overwhelming opposition from the Muslim States, then bolstered by the old USSR; and with the military genius which gave it overwhelming victory in the 1967 Six-Day war. With the support of America as the guarantor of modern Israel; with the strength of a Nation which knew that they had to win every battle, such as the Egyptian/Syrian/Jordanian onslaught of the Yom Kippur War of 1973, when the Egyptians, under the shade of a massive, interlocking anti-aircraft missile defence, manoeuvred into the Sinai over the canal; whilst the Syrians pushed their massive tank regiments onto the Golan Heights; all this made possible by an Israel High Command which simply did not listen to the intelligence reports. They had to literally fight to survive, and of course history tells us that they did so, because they, again literally had to.
The mealy-mouthed British support for a modern Israel: demonstrated by the Prime Minister hosting the Balfour banquet with the Israeli Prime Minister despite the acceptance of the Palestinian ‘Ambassador’ to the Court of St James; trying, as usual, to be all things to all people, and, naturally; succeeding with none.
We should remember the oath which was taken after the truth about the Holocaust was finally discovered; which reads ‘NEVER AGAIN’; after the reports of the Jews being marched off the trains into the Camps which sat, smouldering of death, all across the Occupied Territories!
