Gee, all of this sounds pretty good! But as the author acknowledges, this is all "underwritten by U.S. power." I couldn't have put it better myself. If the cost of maintaining that power is some hypocrisy, then I say: there is nothing wrong with hypocrisy.
The article reaches the core issue but has trouble grappling with it. Would any other approach be better than the one the U.S. is currently taking? Would it be beneficial to the developing nations of the world for the U.S. to abdicate its hegemony, leaving a power vacuum for Russia or China? Or would it instead be better for the U.S. to stop with the hipocrisy, and be clear about its naked intentions to maintain its power? Would the existing multilateral order survive that revelation? Or is the current, if hypocritical, state of affairs the best: for the U.S. to foster the current international order while acting behind the scenes to maintain the power that "underwrites" that order?
