Emmet Scott is another excellent recommendation which I forgot to include on my long list of recommendations

I think those two, the Koran and M&H give one a complete understanding or the philosophy and the actions of Moslems. If you don't have months to read all those others, and I have read most of them, those two are sufficient and complete for comprehension of the nature of the Beast. If then interest is piqued, one should approach the others.
A good take on the Koran, say, the Complete Infidel's Guide, would take less time and be far less tedious than reading the Koran but familiarity with the the Noble Koran, itself makes it more effective to argue and one doesn't have to take a third party's word for it. One has seen the original. Scott lays out the nature of the enemy in historical perspective. After reading M&H which was my first serious read on the subject other than a noncomprehending read of the Koran as a teenager, I came to the conclusion that the War that has lasted 1400 years will continue until every survivor is Moslem or none are. Everything else I have read has pretty much confirmed that.
