IWhat would have happened if Phillip II or his son Alexander would have struck west? How far would they have made it? Would he have had the same success against the barbarian hordes? Would his Macedonian (Yugolslav?) phalanxes have been able to face up to the Franks, Gauls, Nordics and Huns? Could he have set up a Roman-style empire, but hundreds of years before them?
