Why World War I Resonates

That's the title of this opinion piece recently published in The New York Times.  Frankly, it should resonate, because it was the war in which the balance between heroism and blood tipped decisively in favor of the latter, thanks to the introduction of modern technology.  Science, also, does not make war less likely; it only makes it more ruthlessly efficient in snuffing out the lives and hopes of entire populations.

Only we can make war less likely.  I sometimes wonder if we have the will, as well as the wit, to not simply sue for peace, but (ironically) to fight for it.  I hope so.
