Could be seeing the light like Hitchens. Both Fisk and Hitchens are old buddies of Chomsky, the "always find fault with US, US Govt and US Media always lying and distorting crowd", however lately Hitchens almost sounds like Wolfowitz. Hitchens broke off from old Noam, once he realized senility must be setting in. (Noam tried to claim that Vaclav Havel was worse than a Stalinist because he praised the US for their help in liberating Eastern Europe, and because on his first visit to the US, the US was engaged in El Salvadore, and Havel didn't condemn the US during his congressional speech)
Fisk was also beaten senseless to near death by a mob of Afghanis recently, and since his own country is now involved in military conflict in the region, and the Iraqi information minister's propaganda is so thinly disguised and easily disproven, he might finally be realizing the nature of the people he was supporting all these years.
Most of the anti-capitalist crowd during the 60s switched sides after they found out what was REALLY going on behind the Iron Curtain, and in China, and other communist regimes. Fisk, Hitchens, Chomsky, are holdouts. Rather than admit the criminality of the very political philosophy they defended so much, they play semantic games to try to draw moral equivalence between the east and the west.
I think Hitchens, and now Fisk, realize that there is no moral equivalence, and one side is clearly better off for humanity than the other.
The holdouts are simply socialist dead enders like those nutcase Stalinists and Maoists (Workers World Party anyone), and even Nazis, who won't admit they were wrong.
