Venezuela is a direct security threat to the United States because they cooperate militarily with countries like Iran who considered giving missiles to Venezuela that can hit the US.
Because the Maduro regime is still in charge in Venezuela, it seems likely that these military ties will continue, even if they take a temporary pause.
Venezuela isn’t simply ruled by a dictator or a military junta, but by criminals who are in criminal enterprises to get rich. That makes it harder to negotiate away the rulers because the government is actually run by criminals who want to maintain their criminal enterprises.
Venezuela is a more homogenous country than Iraq, and it has a history of democracy before the authoritarian socialists took over.
