Taking the (very) short view, eh? Look to the stats for WWI and WWII. Then look at where we've gone in the past 50-75 years, and the usurpation of the Media and Education in both countries.
...and today there is actual *competition* to the established news media in the form of the Internet and talk radio.
In contrast, what got churned up by WW2 were the warrior cultures of Russia, France, and Germany...none of which have the indigenous fighters today that they had a century ago. ...but losing 100 good citizens per month from a country of 300 Million won't do to us that which happened to France after it suffered 64% national casualties between 1914 and 1918.
