This is true. Chavez is a particularly dangerous dictator because he's a particularly delusional one, sort of on the Korean model. He has been having his official paintings carefully touched up to make him look more reminiscent of Simón Bolívar, for example; and then there's his bizarre habit of referring to himself in the third person. Not a good sign, and I think he's going to be a serious problem for the US and the world in the future.
Most LatAm dictators don't have the ability to become a threat outside of their country. He does. He has been forming alliances with everybody from the North Koreans to the pre-war Saddamite Iraqis (many of whom are holed up in his country) to AQ.
I agree with this analysis. What i find astonishing is the lefties ("the cuba solidarity movement") here in the UK who support Chavez. The Venezuelans I have met studying here really dislike him.
