Not to be a downer here, but the arab armies are hand-me-downs of old western tech.
No one but Israel really developes any military tech in the middle east, the training is sloppy at best and only meant for native land, and the middle east is behind in all things needed for war.
If the middle east tried to go to war, it would be similar to tanks versus a horse.
You lose in:
-You couldn't take over the west anyway with the low population.
-Severely dated and no production of new weaponry.
-Mostly defensive/guerrilla tactics based upon native land.
-Strategically you are surrounded.
Vehicles(ships, planes, tanks).
-You have no real naval force, your planes would get trashed, and your tanks are dated.
Not to mention satelites, intelligence, and practice.
If the middle east went to war, they would be crushed. End of story.
