No. Several nations actually wanted war. Germany felt that war was inevitable and better at that time then latter. Austria had wanted war with Serbia for some time. They both seized the oppurtunity provided as an excuse to trigger the war, expecting victory. Even France had some hawks wanting revenge for the Franco - Prussian war and the return of Alsace-Lorraine.
My history is a bit rusty as well but didn't the empire actually instigate the riots in Sarajevo as well?
I would say that Russia wants war.
China seems to want it too.
Europe and america becoming increasingly nationalistic
A coplex series of coalitions is forming.
Im just saying the idea of it happening is not something we should just dismiss out of hand
This is going to come off as rude so I apologize. You're confusing war with dick waving. Russia doesn't want war. They want to wave their big stick around and maybe try to grab some territory for non-NATO nations that they can get, which isn't much.
China seems content to show off their power but not actually use it.
Nationalism does not constitute wanting a world war so I'm not exactly sure what your point is here.
The way to look at war is to look at it like a chess board. If you suspend the game, you don't gain anything but you don't lose. If you play, you risk the other side getting pissed off and flipping the board on to the ground (Using nukes). No one at all wants that to happen.
