The World Order and the World Systems Theorists

How do you differentiate a world order from what marxist world systems theorists and there are, as you note in your book, diverse and divergent sets of scholars here. I think world system serists have done some of the best work in terms of pointing to parts of global history we've forgotten about. So i'me ye, i'm, i more ond like the barbarian side of the equation, but i i also bear much respect what they have done.
