The Cubans have taught Chavez well..
Probably the Russians, too..
Canada (with an oil services sector employment shorfall) could help things out by granting visas to Venezuela's oil sector workforce. That's the funding source for Chavisism. Some very beautiful women there, too.
Chavez is following the Cuban model well. With Chinese help and Cuban cadres through Venezuela, He could be in power for many years. I think it is wishful thinking that there will be a popular uprising or coup against him anytime soon. A regime change will require much more overt external action than is likely.
