Insurgents is also loaded, and only maybe accurate. After all, it was the United States that overthrew the existing order, which is normally what I think being an insurgent means. Now I guess it depends whether you think the US has established some kind of order there, which would make those fighting against it insurgents.
Or, rebels? Why aren't they called rebels? I think it's the somewhat romantic connotations there, but those aren't part of the dictionary definition of the word. And it's a matter of perspective whether one considers resistance to the US order a worthy cause or not. Our media chooses terms that take the side of the US from the start.
