Unlike all those places you mention, Venezuela has a democratic tradition which was only recently derailed. This isn't some middle eastern theocratic monarchy. It's "get back on track" not "find new tracks where none existed before".
I and many others are asking for evidence of such a plan. The US administration has denied the existence of such a plan.
Maybe those factors you mention will turn out to be relevant or even determinative, and maybe not. I suspect in absence of an actual plan, the mere tradition of democracy will not suffice.
Maduro in prison is an improvement from Maduro still in power. Accept it as a tiny win and move on.
You are aware you're allowed to say, "it'll take some time for this to shake out sufficiently to understand whether it's a tiny win, a huge win, net-neutral, or regionally catastrophic," right?
I'd push the delete button for every unelected dictator on the planet if I could. Repeatedly. It's morally offensive not to.
Things going badly does not mean — even at all — that things cannot go much much worse.
Libya was bad and got worse
Syria was bad and got worse
Afghanistan was bad and got worse
Sudan was bad and got worse
In fact, nearly every really bad situation was already bad, and then it got worse.
