Yes it's a generalisation, but most of the world conflicts throughout the centuries have been religiously based or justified whether you like it or not.
I know that many people want to blame God or Religions, for most of the wars which is the reason they blame and deny God.
Before you go off without thinking. You should get your facts right Mr Grunthos,
World war 1 was about getting another Countries realistate, their were Catholics and Protistants on both sides.
World war 2 was the same, I believe it was a continuation of WW1.
The curent Russia V Ukrane. their Both Eastern orthodox "EXORCIST' Religion just ask him.
The Irish conflit is as a result of the much more powerfull English using their power to anex part of Irland, By the way would you want another country to anex any part of our deserts.
The recent Irak V Iran war was about realistate, since they were all Muslims.
To find a war which may have been caused by Religion I have to go back to the Crucaders, 1000 years ago. (but I'm not even sure about that as well).
BTW, when Countries/People are at war they always call for help often from God even if they started it,
