I don't disagree that colonization was not a good thing. Yet in all of human history we have struggled against one another for dominion of land and resources.

I don't disagree that colonization was not a good thing. Yet in all of human history we have struggled against one another for dominion of land and resources. How is colonization really any different then all the other wars/conquests done before? Or is simply that it was done on such a scale that sets it apart or is it the relative nearness of it historically that brings it more to relevance for people?
