Missing from this assessment of 'leadership', and in any discussion of 'great leaders' as icons is any mention of acceptance of consequences - in another word, INTEGRITY. The icons mentioned became icons, because the consequences of their actions worked out in their favour. 

Not mentioned, however are the leaders for whom the results of their actions did not lead to fame, fortune or personal success, but whose leadership was no less heroic, and no less worthy of replication, in fact, perhaps more so. 

My grandfather was also a war hero; there's a line in the citation for his medal that tells me all I need to know about leadership, and my aspiration to it: "encircled by the enemy, he was given the chance to evacuate by sea. Instead, he chose to fight is way out, with his men".  My grandfather died shortly after the war, I never knew him. There are no schools, no streets, no airports named for him. 

That doesn't make him any less of a leader.
