Rummy had the right idea, he just tested it on the wrong war.
Or as he would say; "you go to war with the army you have, not the army you want."
We're catching up now and in the end Rummy's vision of our future force will be a sound one.
That remains to be seen. But I'll say this, if we end up fighting the North Koreans, or heaven help us the Chinese, maybe even the Iranians, that cheaper lighter force will get lots of kids killed, and perhaps lose a war that is more important than the invasion of Iraq or Afghanistan every was.
