Bit of an oversimplification. Arab states are powerful and have massive numbers on their side on paper, who tried to conquer Israel three times, came close to doing so, and yet failed. Because Arab states are bunch of incompetent fools that run on patronage than by meritocracy. I can’t remember the name but there is a book that analysed why Arab armies are atrocious. Basically, it is because of corruption and patronage culture that value “who you know” than “what you know”. Even to this day, the Saudi-led and funded coalition to eliminate the Houthi rebels of South Yemen could not be extinguished for nearly ten years because of said incompetence by Arab states.
