What do you think would have happened in history if , let`s say, Nabonidus would have been a great king and he would have defeated Cyrus and going on to invade Greece ?

What would have happened if instead of Darius and Xerxes invasion, the Greeks would have faced a great Babilonian invasion army ?

Unlike the Persians, the babylonians had some nice armoured troops. Also, good swordsmen, armoured axemen, war chariots,, armoured spearmen, professional corps of archers, they where good besiegers (borrowed much tehnique from the Assyrians), where quite inovative in terms of warfare, howewer they did not used to raise armyes from subjected nations, so their numbers could not have been that great.

Who would have won ? How you imagine a Greek phalanx facing the Might of Babylon ?
