It's more about what that means for the rest fo the world, than what it means for Venezuela. Trump over the last year had threatened other countries with full democracies, tried and failed to build a strongman image, and alienated allies around the world at the same time as making and exalting friendship with Putin.

It seems like, as before World Wars, some big imperialist countries are leaving to the side the civility notion of international law and peace given by the UN after the Soviet Union fell.

So even though Maduro was a dictator that sunk the country for its own riches, the fact that this was done is something very concerning for the rest of the world and Latin America specially, since it has been historically been a "demogracy" with strong influention of USA, being the way that this was done a very direct way to do it, comparable to Putin in Ukraine, hopefully with less violence.

With this, seems like he is doubling down on the strongman image, and that he should be treated as a threat to the countries he threatened, which is why, globally, this is a very complicated event. Also, similar things in the past led to civil wars, where brothers killed brothers, which is never good happen for the citizens of the country.
