The only thing our political leaders have learned about war is not how to avoid them, but making certain they never again suffer a national conscription, or draft.
Vietnam taught politicians the PR challenges of holding a fine war with a draft in place: All of a sudden, everyone and his brother had some real skin in the game, with so broad a population base up for grabs as cannon fodder.
Today, politicians think nothing of narrowing their gun sights, and sharpening the burden to a fine point -- one supported by very few backs. With a more-or-less volunteer force, you just demand the same small group returns to the battlefield over and over and over -- while promising to look into the puzzling reasons soldier suicides have skyrocketed.
