Lazy nonsense as usual. Both world wars and the Napoleonic war - none involved religion.All sorts of groups have used their 'ideal' for wars Buzzer, but I believe 'religious' wars win the race.
More often than not, wars that are attributed to religion are nothing of the sort and are actually down to a power vacuum, such as when the Brits pulled out of India before partition. Had there been any sort of law enforcement at the time, no way would there have been such large scale death on the India/Pakistan borders. Same sort of thing in Egypt, Iraq and Nigeria these days.
