Would that be such a hot idea, really? We got (and get) all the murderous wars when some regional warlord decides to try it on because, who knows, he might win and besides, it's other people doing the dying. With a single hegemon around, he can't win (tho this still isn't obvious to many) and possibly might have to do some dying himself. That seems no bad thing to me, even though it's not being applied very well because of who's running the US.
I'd think the best thing the US Left could do for the rest of the world would be to catalyse a change in who's running the US.
