I get what you are saying, and why. When you look at Japan in particular, they were monolithic (if that's the correct term ... pretty much one national identity) and easily united behind a leader. The Germans tend to be regimented and, therefore, similar. Iran, Afghanistan, most of South America are more like herding cats ... different reasons but same basic result. S America is a collection of screwed up countries probably due to a temperament prone to corruption and disunity ... a Latin thing we can't fix. So, yeah, trying to fix that on a US model is a problem ... of course, their migrants have no problem with coming here because they like the safety and future that the US model provides them. I'm honestly not sure there is a solution to the Latin temperament with regard to unity and governance.
We can either choose to sit back and watch somebody else fill the vacuum ... Russia, Cuba, China; or we can support a faction. I don't think Russia, Cuba, and China have strayed far beyond the old Soviet Union (Russia Inc if you want to get right down to it). They will back a socialist/communist dictator as always with people coming out poorer for it ... at least the ones still living, or we can wade in and try to do something productive (at least there's not the Sunni, Shi'a, Kurd type issue). We should at least find and support a decent anti socialist leader. Whether there's a right or a wrong set of people in our government to do something right is a good question, but allowing the wrong countries to decide what should be an internal Venezuelan decision is no way to go either.
After congress denied the funds that caused South Vietnam to collapse while Russia and China still continued pumping aid to N Vietnam, Nixon stated:
That course seems to make sense in Venezuela. If there is a reasonable opposition, support them; if they are unwilling or incapable of carrying on the struggle, then don't beat a dead horse. Whether people in this country believe (or the media allow them to believe), the people of Venezuela will be the better for our assistance particularly if dictatorial socialism is defeated.
