@SW-User The UK is not "atheist" but hosts all religions and none - but anyway that is not relevant at all. Actually, the original idea to make an artificial Israel in Palestine was first mooted by the UK!
The decision to do so though, was by the League of Nations, the precursor to the United Nations, largely as a reaction to Adolf Hitler's pogrom against the Jews..
Since Palestine had been a British Protectorate, against Turkey's expansionism, the Arabs understandably felt betrayed by this.
It had never been the USA's business outside of her part in the League of Nations, and it's certainly not China's nor Russia's, now.
