I do consider Nazism to be Islamism but without Allah (this is distinct from being a Muslim, btw, which is something altogether different).
From "The Life and Death of Colonel Blimp", one of the best films of all time:
Clive Candy: I often thought, a fellow like me dies - special knowledge, all to waste. Well, am I dead? Does my knowledge count for nothing, eh? Experience? Skill? You tell me!
Theo Kretschmar-Schuldorff: It is a different knowledge they need now, Clive. The enemy is different, so you have to be different, too.
Clive Candy: Are you mad? I know what war is!
Theo Kretschmar-Schuldorff: I don't agree.
Clive Candy: You...!
Theo Kretschmar-Schuldorff: I read your broadcast up to the point where you describe the collapse of France. You commented on Nazi methods--foul fighting, bombing refugees, machine-gunning hospitals, lifeboats, lightships, bailed-out pilots--by saying that you despised them, that you would be ashamed to fight on their side and that you would sooner accept defeat than victory if it could only be won by those methods.
Clive Candy: So I would!
Theo Kretschmar-Schuldorff: Clive! If you let yourself be defeated by them, just because you are too fair to hit back the same way they hit at you, there won't be any methods *but* Nazi methods! If you preach the Rules of the Game while they use every foul and filthy trick against you, they will laugh at you! They'll think you're weak, decadent! I thought so myself in 1919!
Theo Kretschmar-Schuldorff: [he pats Clive's shoulder] You mustn't mind me, an old alien, saying all this. But who can describe hydrophobia better than one who has been bitten - and is now immune.
Theo Kretschmar-Schuldorff: Do you remember, Clive, we used to say: "Our army is fighting for our homes, our women, and our children"? Now the women are fighting beside the men. The children are trained to shoot. What's left is the "home." But what is the "home" without women and children?
Clive Candy: I heard all that in the last war! They fought foul then - and who won it?
Theo Kretschmar-Schuldorff: I don't think you won it. We lost it -but you lost something, too. You forgot to learn the moral. Because victory was yours, you failed to learn your lesson twenty years ago and now you have to pay the school fees again. Some of you will learn quicker than the others, some of you will never learn it - because you've been educated to be a gentleman and a sportsman, in peace and in war. But Clive! [tenderly] Dear old Clive - this is not a gentleman's war. This time you're fighting for your very existence against the most devilish idea ever created by a human brain - Nazism. And if you lose, there won't be a return match next year... perhaps not even for a hundred years.
We failed to learn in 1945, 1956 and 1989. We failed to learn each year since then. Islamism is just Nazism + God. It is Nazism with the excuse of "Divine Authority".
