The New Yorker had an article by a Yale law professor who seemed to provide a non-bias discussion of the legality and how it differs from other historic interference and control by US presidents. I've forgotten the details of others, although G.W. was a feature player in the story and probably most of them were illegal or borderline. I don't know that any of them proclaimed the Monroe Doctrine or stolen oil as a vague justification. is Panama next to fall?
I could read the article without a paywall, but they seem to be picky about that these days.
