My guess is that Americans who consider themselves left wing tend to approve of Hugo Chavez, as they have, traditionally, tended to approve of Fidel Castro. I would also guess that, like most other people, they tend to disapprove of Bashar Al-Assad and his violent suppression of opposition in Syria.
Chavez, however, is one of the few national leaders to support Assad. Assuming my guesses are correct, how do American (or, for that matter, European) leftists deal with the situation? One might view it, on a much smaller scale, as analogous to the problems faced by communists and those sympathetic to communism at the time of the Hitler/Stalin pact.
