Sadly, I think we are going back to the Crusades somewhere around the 15th century religious wars.
I don’t. Or at least if I understand what you mean. The crusades were a massive coordinated assalt, uhm..... I seriously doubt the West has the will & motivation required to launch anything whatsoever resembling the crusades. Perhaps I am being unduly pessimistic, perhaps I’m naive, but I see individuals, here & there, but not even nations, much less a combined effort of nations as the Western Civilization.
Are you peeking over my shoulder at what I’m reading? ;-)
Crusades defensive then, will be defensive again. Ottoman invasion of Otranto

But haven’t the Imans and the Islamic leaders been putting out the call to act now and might be why we see the esculation.
