Oh, please!

Hugo Chavez should get a life (and a brain, while he's at it):

Venezuelan President Hugo Chavez has urged families not to mark Halloween, calling it a US custom alien to the South American nation.
"Families go and begin to disguise their children as witches. This is contrary to our way," Mr Chavez said during his weekly radio and TV show.
He also said Halloween was a "game of terror", the AP news agency reported.

If Venezuelans (or Italians, for that matter) have started celebrating Halloween en masse in recent years, which I think they have, this means their own culture does not appeal to them sufficiently to stick to traditions and that is certainly not a fault of so-called "American cultural imperialism." If it is anything, it would be a failure of Venezuelan (or Italian) culture.
This is not unlike the ridiculous (and typically French) attitude with respect to Hollywood and McDonalds, which - surprise, surprise - is counterproductive.
