Suffice to say, those who have a background in history,historical research, literature, etc.. will have no problem in understanding the depth and reach of the author’s intent.
I do have a background in those fields and the depth and reach of the author's intent is quite inaccurate -- he could have used different imagery to talk about the war against Islam -- it's like Charlemagne using MOhammad's army as justification for attacking the Saxons.
