The necessity isn't militarized this religion or that religion, though. It's militarized people willing to defend their actual way of life. The West has all but been conquered by a namby-pamby idiotic ideology called Mondialism (One-World-ism) effectively since the 1960s. The Neo-Marxism is a parasite on that worldview that has essentially merged with its host at this point. Mondialism cannot fight back against militarized Islam, on the one hand, and won't, on the other. Neo-Marxism is making use of militarized Islam in perfect alignment with its goals and its commitment to side with any movement against Western Civilization, which is written down on the last page of the Communist Manifesto. Actual Westerners who value freedom, abundance, a good society, etc., who are clear enough to reject Mondialist error, whether Christian or not, very well could fight back effectively against this. The Commonwealth is effectively a Mondialist catastrophe now (and the UK isn't even the worst of it). The EU is a Mondialist project, so Western and much of Central Europe are also fully in its clutches, and its grip is death. MAGA is America's attempt to shake off the Mondialist beast, and it's not going half badly, but it isn't all the way there yet.
