I see this sentiment around here a lot and I just have to laugh.
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.
I can appreciate that but taken to its conclusion it's a recipe for paralysis and complacency. It always could be worse, so let's just let sit here and let shit happen?
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".
