Imo the State Department is pulling the strings here. I.e., commie-bankers.
--he had the support of the air force general with the f-16's. Think about what happened in south america in the past when they actually have for-real serious coups, not this baby coup we saw. Whomever owns the high ground and the serious firepower wins. Numbers on the ground mean zilch. Check ashcanistan for this deal. High ground and firepower, high ground and firepower. There could be 500,000 anti chavez supporters in a mass demonstration, how many jets would it take to disperse the crowd and restore "law-n-order"? One? Probably. Remember, every "leader" always says the same thing, in some word arrangement or other like this -->their opposition are called "terrorists". You are "with" the leader or a "terrorist". Works in every country on the planet, always has, too, until they don't control the serious firepower.
Air power does not float in the air forever like some kind of impervious Zeppelin. An air force is only as good as its ground crew and air bases. The USA can bomb others with impunity because we have air bases all over the world and can fly and bomb anywhere thanks to air-to-air refueling. And that's not taking into account the Navy's aircraft carriers.
The Venezuelan Air Force's F-16s won't be that effective if Venezuelan Army tanks roll over their air bases. Even F-16s have to land to refuel and rearm! But we don't have much info on what is really going on; probably neither side wants to start shooting yet.
