This article is a bit old but I just stumbled across it. It attempts to "debunk" truthout's really well-known article on the matter [seen here]. I don't think there's anything else to say other than it's one of the dumbest articles I've read in a while (even from someone who calls themselves a defender of U.S. foreign policy).
It's a little bit true, like the methodology of the Truthout investigation is pretty bad, like the US is very anti-Eritrea and once gave them $20,000 worth of concrete in a negotiated deal, and Truthout calls that "support".
It's outdated anyway here's the 2023 update: https://www.commondreams.org/news/us-sells-weapons-to-majority-of-authoritarian-countries
