Venezuela is a typical Latin American country with a history rich in political unrest, systemic poverty, and strong-arm authoritarians in positions of power.
I don't see much changing positively out of some revolution. Maduro banned a presidential candidate recently, he may be planning on rigging the 2018 (19?) election.
If Maduro were assassinated or dropped dead the situation would likely only worsen as there would be a power vacuum and surely some attempt to gain power through violence while claiming to be liberating Venezuela from a failed democracy.
Pretty much the only reason Venezuela was ever relevant was because their oil. You can't eat oil.
