Reply #28: They would get stomped. Badly.

Saudi Arabia's major problem in any armed conflict is that it has a hobby army. It's not large and it's full of rich kids who join up because shooting big guns and cruising around the desert in fast four-wheel-drives is lots of fun. (The Royal Saudi Armed Forces are the only military in the world who buys its field cars from Lamborghini--and no, Lamborghini doesn't have a long history of excellence in the production of tactical vehicles. OTOH, if you want a hydraulic pump or an airplane with no wings on it, Lamborghini will fix you right up.) They hire foreign nationals like Pakistanis to do all the lowly admin bullshit like cleaning guns.

You take two countries and throw them into war against each other. If one country has an army full of people who signed up because they pay you to go camping, and the other country has a good army, it's not hard to figure out who will win.
