Honestly, I'm not sure why one would want to restore or instate democracy to begin with- it's a bad form of government. Folks forget, in the USA, only property owners could vote. Madinson mentions that this design was to ensure that the wealthy (those tied to the government, whom lended them money) and well-educated were the intended movers and shakers of the gov't. While the modern USA is a democratic republic, it began with near-aristocratic elements, despite the pandering.
Look, we're not talking some abstract concept of the best form of government here, or 18th century legal precepts. We're talking the modern USA stepping in to overthrow reasonably decent liberal places to live, and replacing their functioning governments with insane death squads. When people criticize the American-backed latin regimes, it's not because of some abstract belief in democracy, it's because those governments tortured and murdered hundreds of thousands of people.
The Colombian right-wing government supporters have a strong reputation for
carving up children with chainsaws. America is directly implicated in the plan to create those groups. And the regular Colombian army isn't much better, they regularly abducted teens, dressed them up as rebels and shot them in fields, then claimed they killed rebels in firefights, because they get cash bonuses and promotions based on kill-counts. All well documented and going on at least as recently as 2008 (I haven't kept up with the news). Colombia also leads the world in trade union murders. Literally leads the world - some years over 50% of the worldwide union-leader murders were in just Colombia. Yet Bush jnr called them a model democracy that the rest of South America could learn from.
Colombia are a "democracy" in name only, and by far the most brutal government in the hemisphere. The right-wing party has private death squads that target anyone on the other side of politics, and they are "somehow" the biggest receivers of US military aid in the western hemisphere. They are a basketcase and the single biggest military threat to their neighbors of any south American country. Yet, Bush was propping them up and trying to turn them into a superpower: in 2008 they bombed Equador and threatened Venezuela when Venezuela spoke out against the bombing. Colombia and USA denounced Equador/Venezuala (which were once under Colombian rule) as terrorist states. Colombia was gearing up to start a war of aggression (they have the biggest army in south America) and America was saying they'd back Colombia. It was only averted when literally everyone else in South America formed a regional military alliance to avert the war. USA then
talked down this regional alliance (now known as the South American Defence Council) as a flash in the pan, whereas they were
talking up a rogue right-wing nation basically declaring war on all it's neighboring countries. So, yeah, excuse me being cynical about the USA supposedly coming in to restore order.
