Should the u.s help with south american dictators?

South American dictators have always posed a huge problem for their countries. For this, I will heavily rely on Venezuela as an example.
In the late 1990’s to the early 2000’s, Venezuela was one of the most successful oil giants in the world. However, due to actions taken by Hugo Chavez during his rule, Venezuela’s oil production and profits have fallen dramatically. 
Its current dictator Nicolas Maduro has only worsened the economy ever since he first took power. Like many other corrupt rulers, Maduro seeks power. He wants to expand his reign as much as possible, silencing anyone who stands in his way. In my opinion, and I believe many others, the U.S. should most certainly do something to help people fight back against their dictators. However, while we all want this to happen, it won’t any time soon. To start, the U.S. has its own problems at the moment. They’re busy trying to pass new laws now that President Trump is back in office and also negotiate a peace talk (supposedly) between Russia and Ukraine. 
Moreover, if the U.S. did engage, it would only result in a war, distracting the government from more pressing matters. On top of that, the U.S would gain no practical benefits or advantages from doing this. It would only be a waste of resources resulting in a larger loss than win for the U.S. Furthermore, this might spark backlash from allies, thus prolonging the war and loss of resources and funds. Backlash could also stem from citizens of both the U.S. and Venezuela. While few, there are some citizens that support their dictators and fully endorse their plans.Citizens of the U.S would also protest, more than likely, due to the fact that it would again distract from other much more pressing matters. The U.S. doesn't have any technical reasons to invade a South American country at the moment, although President Trump has stated intentions on invading Panama to retake the Panama Canal. We can't just start a war just because we believe a country's leader is cruel and unjust. We must have some viable explanation and reason to launch and attack, which is currently absent. Maduro, for example, is unlikely to give us one. Although cruel, he is smart, and knows that launching any sort of offense against the U.S. could result in major consequences for his tyranny. Not just this, but many spies, news reporters, and other civilians have ventured to Venezuela and have “disappeared” under mysterious circumstances. 
I’m going to share a quick personal story. My mother was born and raised in Venezuela, but settled down and had a family in the U.S. Unfortunately, my grandparents were still stuck in Venezuela. One year, she had to go and get them to the U.S. when things were starting to look really bad there. She was lucky to get back, as it’s very hard for people to leave Venezuela once they enter, and this process took her over four months to accomplish. 
So, should the U.S do something about these dictators? How much I want to say yes is immeasurable, however I must say no. There are just far too many cons to outway the pros, so for now, we will just have to wait.
