>>5You're comparing countries during wartime to countries living in peace half a century later. Hardly a fair comparison. I wouldn't even consider high birth rates as a good thing nowadays, there's too many people and they only benefit those in power, and declining birth rates are usually a sign of a developed, educated country, anyway. Lowering mortality rates and improving life conditions would be more important to me.
Also, Mussolini's Battle for Births was a failure, and crude birth rates under Nazi Germany were half as much as they were during the beginning of the 20th century. I guess you could count Franco's Spain, which maintained birth rates, and the Japanese empire, which had quite a boom after it fell, and even with a negative population growth, Japan is still considered overpopulated today, so it's not like they need high birth rates at the moment.
