Just put sanctions and encourage allies and neutral states to stop supporting or dealing with the Chavista regime. Take in their refugees and encourage the other nations, looking at Peru here, to do the same.
The problem with that is that it doesn't encourage a regime change, and we'll end up becoming a 21st century Cuba. And our neighboring countries can't take care of our refugees if they don't get help from outside.
I highly doubt Maduro is as charismatic to survive than Fidel, also I would be supportive of giving aid to the refugees across latam.
