Those sentences are true, but I don't know why you typed them.

Was the Franco-Prussian War fought for religion? The Russo-Japanese War?

no, i don't say

just this is the first world and it is non-religious

I guess I'm still not quite clear on the message. 

Anyway, there's another point to keep in mind about WWI: it's often considered the death point of 19th century rationalism. In a sense, it made people think differently, and less optimistically, about science. 

Briefly put, the amazing gains in science in the 19th century, and the gradual movement towards democracy in place of irrational inherited power, made people optimistic. Scientific rationalism, they thought, would bring a peaceful world. 

Many people had this optimism destroyed when they saw scientific gains being used to kill people more efficiently. Poison gas rather than medicine, bombs from the air, etc. And it turned out that democratic leaders could be as stupidly violent as kings. 

So the optimism we still see sometimes (in Sam Harris, for example) that if we just let science lead us things will be OK seemed then not to be warranted.
