Seriously you're like a walking example of Poe's law. Next you'll be telling us Hitler was all well and good because he put paid to the German Communist Party.
Maduro is an uneducated bus driver who only got to power by being a personal driver for Chavez. He doesn't know how to rule the country, and as a result he ruined Venezuela, turned it into a complete mess by indiscriminate nationalization and heavy-handed governmental interventions. Don't try to shift the blame here - it's Maduro's fault that his country is now starting to rebel against his tyrannical rule. Hopefully he will be deposed swiftly and without too many casualties.
Maduro is a huge power-hungry moron. But here's the problem: the people opposing him are also power-hungry, and while not morons they don't give a shit about anyone other than themselves (not that Maduro does either).
I know you are firmly in the camp of neo-liberal capitalism and don't really mind that, but this is not a conflict between capitalism and communism. This is a conflict between a sycophant-turned-leader and oligarchs.
External intervention is also not going to work either. If the US intervenes, everyone in the continent will, with reason, be extremely pissed off. Last time the US decided to mess around in South America... well, just do some research on Plan Condor. Fortunately, Trump leans towards isolationism. If anyone else in SA intervenes, they'll either prop up one side as their puppet, try to put in a third puppet of their own, or maybe even an insane attempt at outright conquest/submission if it is Colombia.
