I notice that people in general just gloss over and handwave the great war. It baffles me.
WWI is a textbook example of what happens when institutions are on their last leg and enter the anger stage of greif; what happens when keeping it real goes wrong (keeping your own interest in mind)
It showed the world how disposable life can be when it comes to said interests. It showed the world how human suffering can be wrought for the shittiest of reasons.
