Sometimes enthusiasts imagine an army can advance at the speed of a fast armored personnel carrier on the road. The reality is that any military formation travels at the speed of its slowest component if it wants to remain a fighting unit.
It is no use arriving early if you are on your own, out of fuel, out of ammunition and out of ideas. The arithmetic of logistic support over extended distances is sobering, and militates against the short war. Even President George W. Bush seems to be realizing that now.
