American defense contractors are also business leaders. They practice capitalism. Allowing them to sell nuclear weapons or B-2 bombers or Ohio class boomers to North Korea and Comrade Kim might be one example of "Free Trade Communism" as well as one example of gross and counterproductive stupidity. It's easy to come up with other examples if you really try!
I think that would more appropriately be described as mercenary capitalism than communism. Unscrupulous capitalism, ie, putting profit above any and all moral concerns, is certainly not laudable, but neither is it communism. Communism by its very definition entails state ownership of enterprise, which again, by definition precludes the profit seeking motive of the individual.
