> Roosevelt and Admiral Leahy set policy and war strategy, not the joint chiefs <
Agreed. By “hands off” I meant that FDR did not interfere with operational decisions. For example, he did not decide which divisions hit which beaches on D-Day.
On the other hand, Hitler interfered on pretty much every level. For example, during the German defense of Cherbourg Hitler drew lines on the map where the German forces should be. Those lines did not correspond to the terrain, or to anything else. They were pretty much random.
That would have been Churchill who micromanaged.
Also for the last year of Roosevelt’s life Admiral Leahy was the unofficial acting President of the U.S., due to FDR’s health problems, something few people even knew about, he served on active duty for 62 years.
