Responsible Statecraft is not “far leftist media with anti-American spin.” It’s actually a run by billionaire funded think tank which only accepts donations from within the United States. The author of this article is also the former senior editor of The American Conservative magazine.
I mean, the original article isn’t even biased towards the left. It’s just anti-interventionist but also actually recognizes what it calls prior successes of ECOWAS intervention and argues in favor of advancing American interests. The person you’re replying to is just paranoid about “leftist media.”
