The title signifies ""mobilization day"" -- the day America mobilizes for war. The facts exposed in recent Senatorial investigations of the Nye Committee form the basis of this analysis of the steps leading up to the war -- and the events leading up to another war today. The data has been adroitly brought together -- and the results speak for themselves (though one can't help but give a backward glance at omitted evidence in other directions). Nothing startlingly new, to those who followed the investigations. But the premise and the findings are a challenge. Not in the class with The Road to War.
