If all or any ideas in conflict are "wars", then maybe yes.
If all belief systems are "religious", then maybe yes.
BUT, if you want more than trivial definitions, keep digging. (Look at oil wealth, too, if you really want to understand the political roots of conservative societies).
P.C. formulations from the Right about whether this-or-that conflict should be fought as a "war" and what is truly "religious" and what isn't perversion dressed up as religion aren't any help, either.
