This seems out of date. World War II is not going to be repeated. WW II could drag on as long as it did -- giving civilian-to-war conversions enough time to matter -- because there were no nuclear or precision guided weapons. If a no-holds-barred Total War breaks out between major world powers again, it's really hard to see how it would last long enough for factory conversions to be meaningful. And if it's just another big war of choice we're imagining in the future, like Americans fighting in Iraq or Vietnam, those haven't been bottlenecked by industrial capacity either.
