What kind of war do you think is being fought in Gilead?

From the text, we can infer that the people of Gilead are in rebellion against their communist state.

I haven't read the book, but in the show at least I think it is actually more of a civil war than a rebellion, because we know that there still is a United States government separate from Gilead, and they refer to the front, as opposed to the battles being fought guerilla style in the streets like you'd expect to see if it were just the citizens of Gilead rebelling against their own government. I wish I could see a map to better understand how much of the country is Gilead and how much of it remains the USA.
