" Europe’s very success in surviving those earlier crises paradoxically led to a dangerous complacency in the summer of 1914 that, yet again, solutions would be found at the last moment and the peace would be maintained. And if we want to point fingers from the twenty-first century we can accuse those who took Europe into war of two things. First, a failure of imagination in not seeing how destructive such a conflict would be and second, their lack of courage to stand up to those who said there was no choice left but to go to war. There are always choices. "

― Margaret MacMillan , The War That Ended Peace: The Road to 1914
