To quote the witch in Snow White "Who's the fittest of them all?" Who but those who think they are powerful enough to occupy colonies who supply raw materials to be shaped into manufactured articles, to be sold back to the colonies?
That is the definition of imperialism. It is the colonization by force of those unable to prevent the colonization. Imperialism is the creation of an empire by colonizing people that can't prevent their own subjugation.
Does that not sound like survival of the fittest to you?
I would have to say that Justinians empire was weak after being split into. He also faced criticism for the rise in taxes due to the war effort.
