True but the only really relevant ones are Iran, Saudi, Turkey, Qatar. Sunni or Shia is the dividing line, Turkey will side with Saudi and by default Israel, Qatar want to become Westernised but can't help themselves so fund Hamas, although now distancing themselves from them. The Arab nations have enough problems and divides between themselves, whilst still graduating toward normalisation with Israel. Iran are the main outlier and are still sworn to the destruction of Israel.
It's interesting to note China's change of language toward Iran, not such a staunch supporter as they were 6 months ago, they're not stupid.
The landscape of the Middle East is evolving, changing for the better, Israel and Saudi will be at the forefront of this.
Starmer's not stupid either judging by recent statements regarding recognition of Palestine as a state.
