Well, I didn't make a comparison study between the two articles but I just read the first ones on Pinochet that you said were "very negative" (Military coup of 1973 and U.S. Backing of the Coup) and they don't seem negative to me at all, pretty mild if you ask me. This overthrowing of a government would be the equivalent of Castro's revolution so I don't get your point sorry.
First time I've ever defended Castro even partly. :-)
>>This overthrowing of a government would be the equivalent of Castro's revolution
Arguably, Castro overthrew a dictator. Allende was, afaik, quite democratic(?).
Castro did break promises about general elections. He took over and got military/economic support from other dictators.
The main difference is that today Castro+family are still dictators of Cuba -- while Pinochet and his junta are gone since a long time, leaving a quite nice country.
And this is totally off topic for HN and the article, of course.
