Everyone on the true left knows that the Columbian government has been highly fascistic, corrupt, and death-squadish at the very least. However, reading this article as a novice to the issue, one would think that, that's not a known thing and that there's doubt about who's largely responsible for the killings of "defenders of human rights" there.
Meanwhile, Columbia is called a great ally of the USA but Venezuela is under heavy sanctions and threats (even though the governments of Chavez and Maduro never engaged in anything remotely like what Columbia's government has done and is still doing).
This is why the US is considered a joke internationally when it comes to consistency standing up for democracy and human rights, etc. The US stands for its plutocrats and nothing more.
