From my dialogue with Daniel Larison over at The New Inquiry:
In the American context, there is a precedent for the conservative rush to empire, which you suggest is mostly a creation of the Cold War. And that is the slaveholders. But the slaveholders developed a fascinating vision of an imperial political economy, which would be centered around the Mississippi and spread out from there to the Caribbean Basin and beyond. It would be centered on slave labor, and it was thought to be a different kind of imperialism.
And though I’ve never seen anyone discuss this, it strikes me that there are fascinating parallels to be drawn between their vision of a slave empire, based on land, and the Nazis’ vision of an empire in the East, which was also to be based on land. People often forget that Hitler had a major critique of European imperialism in that it was extraterritorial and commercial in its orientation, whereas he wanted an empire that was contiguous territorially and based on slave labor and agriculture.
