The Cedar Lounge Revolution

I know that cross posting from other blogs is not usually the done thing. But, I saw an interesting point made over on Crooked Timber on the occasion of the 91st anniversary of the ending of WWI, and I will stick my neck out and break that protocol this once:

The cataclysm of the Great War brought forth monsters like Hitler and Stalin, who killed millions. But the War itself, with the millions and tens of millions of lives it took, directly and indirectly, was loosed on the world by political leaders more notable for mediocrity than for monstrous greatness.

The names of Asquith,  Bethmann-Hollweg, Berchtold and Poincare are barely remembered, yet on any reasonable accounting they belong among the great criminals of history. Not only did they create the conditions for war, and rush (eagerly in most cases) into it, they carried on even as the death toll mounted into the hundreds of thousands and beyond. Even as the original grounds for war became utterly irrelevant, they continued to intrigue for trivial postwar benefits, carving up imagined conquests among themselves. Eventually, most were displaced by leaders who were marginally less mediocre, and more determined to win at all costs (Lloyd George, Clemenceau, Ludendorff, Hindenburg and others).

How could such ordinary, seemingly decent, men pursue such an evil and self-destructive course, and yet, in most cases, attract and retain the support of their people? I find it hard to understand.
