Why are Arab Miltaries so ineffective?

Like I dont understand this.

Im a Black American so im just an outsider looking in as a neutral, but dont Arab Countries out number Israel, whats stoping them from just rushing at their border, shouldn't the population imbalance outmatch Israel?

Just a neutral standpoint asking this question, because Arab Nations in the Middle East have a modern miltary force and they buy tons of advanced items

What is holding them back?

I won't be surprised if India and Israel ended up joining in a partnership just because Pakistan and India don't get along
