The 9/11 Conspiracists and the Decline of the Left

Here is a quote from Alexander Cockburn: The 9/11 Conspiracists and the Decline of the Left.

Five years after the attacks, 9/11 conspiracism has now penetrated deep into the American left. It is also widespread on the libertarian and populist right, but that is scarcely surprising, since the American populist right instinctively mistrusts government to a far greater degree than the left, and matches conspiracies to its demon of preference, whether the Internal Revenue Service, the Federal Emergency Management Agency, Black Helicopters or the Jews.
These days a dwindling number of leftists learn their political economy from Marx via the small, mostly Trotskyist groupuscules. Into the theoretical and strategic void has crept a diffuse, peripatic conspiracist view of the world that tends to locate ruling class devilry not in the crises of capital accumulation, or the falling rate of profit, or inter-imperial competition, but in locale (the Bohemian Grove, Bilderberg, Ditchley, Davos) or supposedly "rogue" agencies, with the CIA still at the head of the list. The 9/11 "conspiracy", or "inside job", is the Summa of all this foolishness.
