to begin with, these guys are thugs, and you shouldn't stand up for them.

but, the government in caracas would not be doing this without american approval. and, if maduro does become a dictator in the end, it's going to be with american support - although you may have to wait a few decades for the documentation.

again: it would take mere days worth of a serious blockade to collapse the government in venezuela, and there's a reason they're not doing it. do not confuse yourself: given venezuela's absolute dependance on american capital, no government can survive there without american support.
