A quick refresher in world history. Prior to World War I, the world was a huge ball of molten slag and gaseous muck. But that's not important right now. Immediately prior to World War I, the world was divvied up into huge power blocs, basically known as empires.

A relatively unknown loser (no offense to the PowerLine guys, Freep, et al.) shot Arch Duke Ferdinand and the whole house of cards came down. Some empires were obliged to help their allies. Others were just greedy, seeing opportunities in others' weakness.
