surely though Hitler's lack of involvement could have been seen as a stength, he did not need to go to meetings because people knew his ideas/thoughts/feelings on subjects. Hitler also was able to pass the enabling making him able to pass laws without the presidents permission therefore he was the most powerful man in germany.
When Hitler did get involved his opinion went in unchallenged, therefore he had ultimate power.
Hilter, also believed in Darwinism, hence could explain the reason he let his subordinates battle it out.
"Darwinism?"
I'm glad you didn't come here with an agenda . . .
By the way, far from being uninvolved, one of the main reasons the Germans suffered so badly in that war was Hitler's insistence on "micro-managing" the war. Tens of thousands, and possibly hundreds of thousands of Germans lost their lives because Hitler insisted that they must not surrender and that they must not retreat. A quarter of a million Germans were captured at Stalingrad alone--von Paulus was promoted Field Marshall by Hitler, who insisted that no German Field Marshall had ever surrendered. When his officers pleaded with von Paulus to attempt to break out of the city, he was horrified by the thought of disobeying his orders from Hitler.
Hitler ordered a similar "no retreat, no surrender" policy for the Axis armies in North Africa. Rommel described Tunisia as the largest self-supporting prisoner of war camp in history. When the North African campaign finally ended, the Germans and Italians had suffered over 200,000 casualties, and 275,000 Germans and Italians had surrendered when they could fight no longer. Italy was effectively removed from the war.
I don't know what you mean by uninvolved, but from a military perspective, Hitler was too involved.
