Problem is that the leftist chavistas have a duped half of Venezuelans still on their side.
Yes, and they also have Leftist militias and paramilitary groups that are well armed and organized.
The Left here in the US have no such thing. They’ll need to rely on professional institutions to preserve order and their power, rather than ideological foot soldiers, if a collapse comes.
And my guess is that members of the professional services (law enforcement, military) won’t react positively to being ordered to engage in the kinds of things (armed intimidation/terrorism, death squads) Leftists in other countries ultimately have to rely on to maintan power and control.
