The point is clear. Even if, as Mr. Yglesias says elsewhere, it might be that "the cakewalk scenario, though wrong in retrospect, was the best reading of the available evidence," Rumsfeld's force planning was still lousy.

It's his job to plan for all cases: so that there is not just a path that leads to victory, but all (or almost all) paths lead to (rapid, nearly bloodless, and decisive) victory.
