Haven’t read Skousen’s book. But I just went to your link and read the Communist Manifesto. It’s not really accurate to call it the Party’s Manifesto, because it seems to me that implies it was produced by the Party. And of course it preceded any Party by decades.
I see little correspondence between the Manifesto and this list. The list describes a bunch of tactics by which the Party will supposedly achieve its goals. The Manifesto is a sweeping description of the past, present (1848) and future of the world. Most of which has not at all come true, and for that matter has little to do with the actual practice of Communist parties and governments.
