Uhh, dude, if you read your history then pretty much everywhere has invaded everywhere else at some point, and populations that aren't being invaded are just as often killing each other.
So while it happens, it's not a data point here.

And the killing off part was mostly a reference to diseases brought (without intention) to the Americas that more or less killed the civilizations there.
But maybe I'm just brainwashed by the people on the left.
(Yes I know, most of it is still designed/developed in the west..)
Not really. Europeans essentially invaded and colonized the western hemisphere, Africa, India, Australia, etc... and yet none of the reverse happened. The Aztecs did not land on the shores of Spain. The Zulu did not invade France. (About the closest you can point to is the Turks besieging Vienna.) If you've ever wondered why europe dominated the new world & africa and not vice versa, I highly recommend Jared Diamond's "Guns, Germs, and Steel."
A Farewell to Alms is a much better book with way more hard data than Guns, Germs, and Steel. It builds a solid and excruciatingly researched case that beginning in the middle ages unique demographic forces shaped the European genome and culture (eugenic forces). Diamond's conclusion that it was geography and nothing else pales in comparison to Gregory Clark's case.
I guess we'll know in a few decades if the balance of power has shifted over to Asia or not.
