That's the most ignorant thing I've ever seen. So, let me get this straight, by pointing out loose similarities between two actions that you (the creator) deem wrong, nobody is allowed to call the later instance wrong? So, forgetting about the spread of Communism (there's no point in even trying to convince the creator of this that Communism is a bad thing based on the examples they give), we are to assume that Terrorism against the US is okay because funding the Contras was wrong? Trying to counter Iran, who had just previously engaged in kidnappings of Americans a few years prior and had declared the United States a sworn enemy was wrong because the US chose to enlist Saddam to do it?

Justifying a "wrong" by pointing to another "wrong" is never a strong argument.
