It’s possible to draw analogies to the Spanish Civil War anytime there is a major left/right cleavage. But in our case, I think the civil war in El Salvador is a better political analogy in terms of parties, factions, and their relationships, and I think the Lebanese Civil War works better as an analogy in terms of sectarian/tribal conflicts. El Salvador and Lebanon are comparable in size to our individual states. “Civil War Two” in the US would be those two civil wars synthesized and multiplied by 50.
