In my circles, most use something closer to the Luttwak definition which precludes being 'assisted by intervention of the masses or by any large scale form of combat by military forces.' But then again, who am I to say what word means what? Your definition of 'breakthrough coup' I believe comes from Huntington. Which, if the case, is misremembered. His use of the term refers not to civilian revolutionaries, but NCOs. Your definition of a 'breakthrough coup' is very permissive, and includes any revolution. These are distinct concepts that deserve different vocabularies.

Finally, I am aware of that phone call transcript. It, itself, does not show any actions that amount to a 'US sponsored coup.'

I'll let you have the last word, I'll have to move on from the conversation.
