I've heard The New Atlas recommend them regarding their analysis of the military situation in Ukraine, but other than that I don't know much about them.

They are paleo conservatives.

They dislike the traditional right and liberals, and oppose interventionism. Simultaneously, they hold reactionary social views. On economics I haven’t heard them say much. Often times, they will mostly avoid social issues in their programs, and focus on mostly factual news—diplomatic, military, and economic.

I think the appeal for leftists is that they are ostensibly anti-imperialist, however they are still reactionary. In this regard though, they are still perhaps closer to criticizing capitalism accurately than some of the American “left”, since one of the most important elements of capitalism is imperialism.

In effect, it’s a bit like how a liberal might claim progressiveness on social issues, but be blind to imperialism. At the same time their social critique will be lacking and to various degrees superficial. Their critique of what we call imperialism is what might be called a critique of interventionism.

Accordingly, the Duran presents a view indirectly and sometimes directly critical of imperialism, which stems at least in part from the international relations theory that great powers weaken themselves when too interventionist. While they may not have a critique of capitalism in their analysis, they do cover both some of the internal rot in the imperial core, and present most of the critical developments of multi-polarization.

Since these developments are crucial, the Duran can be a decent source of news for some topics, on the condition that your familiar with their position. Perhaps since they have become increasingly resigned in support for the imperial core, and more supportive of anti-imperialist states for reasons other than ours, their content is more approachable for leftists.

Nonetheless, they are reactionary.
