@titans62 - I completely agree with you that it was a matter of the leaders of Europe not knowing what they were doing and seeing the dangers of the alliances. However, the Central Powers deserve a lot of blame.
The Central Powers involved Germany and a few very volatile countries that could end up sparking a World War. This was known among many leaders of Europe and that it was in reality an inevitability.
Once studying the era it comes to no surprise that the assassination of Archduke Franz Ferdinand caused countries to be drawn into World War 1 and that the Central Powers alliances were the major cause of the War actually starting.
