Islamic Fascist Death Cults

The United States is currently fighting a war.
It is a war whose breadth rivals the Cold War and World War II.
The most accurate label for this war that I have heard is a war against Islamo-Fascism.
I prefer to narrow the parameters somewhat with the addition of Death Cults. I believe that we, and even the entire civilized world, are at war with Islamic Fascist Death Cults.
To promote clarity, I wish to be unambiguous about the terms I am using.
The enemy we are fighting is Muslim. There are other terrorist groups in the world, but the world wide, intentional murder of innocents, has only been enacted by Islamic groups. Terrorists, claiming that they are acting in the name of Islam, have struck at innocent civilian targets in nearly every country on the earth. This is not true of any other terrorist group or philosophy.
The enemy we are fighting is fascist. Fascism is commonly understood to be a philosophy; a political movement; or a government marked by centralization of authority under a dictator with stringent socioeconomic controls that suppresses the opposition through terror and censorship, and typically has a policy of belligerent nationalism and racism. The present Islamic terrorists make the claim that Islam is the only philosophical system that should be allowed to rule; they believe in following a single authority figure; they believe that it is only the Islamic elite who follow their cause that should have control of their economic means; they believe that the murder of innocents is an legitimate tactic in this philosophy; they believe that no other, besides themselves, should be able to speak; they believe that their Islamic philosophy is destined to rule and that all other philosophies should be crushed.
The enemy we are fighting glorifies death and believes that it is the highest philosophical statement that one can make. In this, the Islamic Fascist Death Cultists differ from other Muslims who might wish to see Islam imposed upon the entire world, but who take seriously the prohibitions in Islamic Sharia Law against suicide and the murder of innocents. The Islamic Fascist Death Cultists have created a new Islamic philosophy which is akin to human sacrifice. They believe that their G-d is pleased with the blood of suicides and the blood of those they murder. While this belief is not unique to this group or this time, it is the commonality that ties Islamic Fascist Death Cultists together. They have made a cult out of the death of innocents, no matter what their religion - the innocent victims could well be other Muslims. The thread that ties Islamic Fascist Death Cultists together is their wish to see other human beings suffer and die in the name of their G-d.
This is the war we are fighting. These are the people we are fighting.
There is one additional factor.
The parent group of these Islamic Fascist Death Cultists, which is Islam in general, does not appear to be trying to stop or thwart their Fascist Death Cult progeny.
This seems to be the crux of the problem in our war against Islamic Fascist Death Cults.
How is it possible, or is it possible at all, to get the leaders; the rulers; the religious authorities; the opinion makers; those who do not believe that Islam promotes the death of innocent victims; to categorically condemn and fight against these Fascist Death Cultists who have usurped their religion?
If the majority of Muslims believe in this Cult of Death, then the United States and other civilized peoples need to recognize this and condemn and fight against Islam everywhere.
If it is only a minority of Muslims that believe in this fascist Cult of Death, then the majority of Muslims need to reassert their authority by proclaiming these Death Cultists to be evil; non-Muslim; and condemned to Hell for their actions.
Why can't the religious authorities of Islam simply state that those who murder innocent people, be they Muslim or non-Muslim, are forever removed from the grace of their G-d and forever condemned as heretics and apostates?
