He states openly: all the useful idiots will be rounded up and shot, because after they find out that a) in the New Marxist-Leninist state they will not be in power and b) its not a very nice place to live if you aren't in power, they will revolt. And former useful idiots make very deep enemies for a Marxist dictator. So they get shot first.
And the money quote: "If this happens (the Marxists come to power) there will be no where for you to defect to like there was for me. Unless you want to move to Antarctica and live with the penguins".
