First you need to know that Saudia or any gulf country haven't participated in any war against israel .. it was mainly Egypt and sometimes Syria plus Jordan.
and If you want to say that Egypt was defeated, then yes , but let me enlighten you some info .. in 1956 we were attacked by 3 nations at same time (england,france and israel) . in 1967 the U.S aided israel with intelligent info through 4 planes ( RF-4c phantoom) you can find these info in the book (taking sides) by the author steven green, they had top notch tech and we didn't.
the USS liberty (that was attacked by the zionists ) was spying for israel. funny isn't it ?
and clearly we weren't defeated in 1973 even though the U.S aided israel through operation neckel grass.
so what are you talking about ?
