This kind of sharp ideological turn is typical for outbreak of wars.
From what I have read, both the 1870 Prussian-French war and the outbreak of WWI in 1914 were followed by huge outpouring of militarist attitudes, even though there wasn't even radio (much less TV or Internet) and most common people didn't read newspapers, or rarely so.
We seem to have a collective subroutine for turning into murderous apes in our societal firmware. It was probably adaptive once. It may not be as adaptive in the nuclear age.
