Nkrumah, the Cold War, the Third World", and the US Role in the 24 February 1966 Coup is supposed to appear in Bea Lundt and Christoph Marx, (eds.), Nkrumah Today (Stuttgart: Franz Steiner Verlag, 2016). But, I haven't heard anything from the publisher in a while. At any rate I have put up a draft of the chapter on my academia.edu site for anybody that wants to read it. You can read and download the paper here.
