On this edition of ST, we speak with the popular historian whom H.W. Brands has called "a master of the historical moment" -- Jay Winik is our guest; he's the author of the bestselling "April 1865," among other books. Winik talks with us about his newest volume, which is just out: "1944: FDR and the Year That Changed History." As was noted of this work in a starred review in Kirkus: "An accomplished popular historian unpacks the last full year of World War II and the excruciatingly difficult decisions facing Franklin Roosevelt.... Winik asks whether, by focusing so wholly on winning the war, Roosevelt missed 'his own Emancipation Proclamation moment,' the chance to make the war about something bigger, specifically 'the vast humanitarian tragedy occurring in Nazi-controlled Europe'.... The author's fair assessment of the evidence, detailed scene-setting, deft storytelling, and sure-handed grasp of this many-stranded narrative will inspire any reader to rethink this issue. Do we ask too much of Roosevelt or too little? [This book offers] a complex history rendered with great color and sympathy."
