What's interesting to note is that virtually all of these battles have been West vs. West or East Vs. East, rarely ever the West vs. the East.

Seems to me that the only time East vs West wars happened was through some kind of invasion involving Nomadic tribes in Central Asia, and the only real West vs East conflicts are found during the 19th century when the West industrialized and the East mostly did not.
