LBJ was a globalist at heart. The first two Kennedy bothers were mostly Americans at heart.
Bobby had served as a staffer of Sen. Joseph McCarthy but devolved into more of a globalist after his brother's assassination, but still had not made the complete transformation. Remember, his assassin was a Jew hater who did not like the Kennedy family's tilt to Israel.
There doesn't seem to be a solid purpose to driving every successful African state to chaos & poverty. Expanding communism may have once been the goal, supplying bodies & resources to fuel more communist expansion. But that (as far as I know) was contained to Africa.
The three objectives I can see are: denying other nations the resources of Africa, a powerful source of destabilization that can "used" by dragging nations in or moving people out and building upon the results, a massive wealth theft & "redistribution" mechanism through which individuals & organizations gain power & wealth and unsustainable governments are funded.
This can't be random, not with the U.N. and communist countries doing the exact same things, over and over.
Have we witnessed large-scale socialist experimentation ?
Agreeing that LBJ was a Globalist/near Communist, why did he push so hard to escalate our involvement in VietNam?
