Some have argued that it sowed the seeds of WWI,
That is laughable ! I studied European history in college and during that time all the major countries in Europe went on a Huge military buildup while forming secrete alliances. These guys were spoiling for a fight, and Any excuse would start it.
Think about it. A Serbian terrorist throws a bomb into a car that kills The Arch Duke and his wife started that Damn War!
Agreed. The Germans were biting at the bit to go to war. In those days war was still viewed in romantic terms. That ended when men saw their comrades torn apart by machine guns, asphyxiated with chemicals, shelled and made to endure trench warfare.
