I can't help but wonder, though
...if one of the reasons the Arabs have typically fought so poorly against Israel is that the rank-and-file simply wasn't motivated...meaning, Israel wasn't pushing their backs against the wall, wasn't trying to eradicate them. Win or lose, the Arab soldiers could simply go home afterward.
The Israelis, on the other hand, fought brilliantly, as if their very existence depended upon it.
I know it's hardly a scientific analysis, but I do find it interesting. The Arabs, apparently, can start war after war--and lose war after war--with relative impunity.
It would be my bet that Israel would only be able to lose once.
