Empires, including the "invisible" corporate-based empire we have today, aren't built from nothing. Key players fulfill key roles to get and keep the empire running. Taking from James Corbett's podcast archives, originally posted on August 30th of 2015, here's one of the biggies: Allen Dulles. I'll let Corbett do the rest:
Diplomat, spy, Wall Street lawyer, philanderer, government overthrow specialist, Nazi collaborator, MKULTRA overlord, presidential assassin. This week on the Corbett Report podcast: meet Allen Dulles, fascist spymaster.
