Dunkirk and the leadership lessons can be drawn from the movie and historical events. If you have not seen it, I suggest you go to see what I believe is the summer’s top movie, Dunkirk. It is great cinema, has a good history, and presents the view of soldiers on the ground from the English perspective. It unfolds on land, sea, and air; in decreasing time frames of one week, one day, and one hour. I was lucky enough to see it on glorious 70MM widescreen, so the resolution was outstanding. I believe several leadership lessons can be learned from the British (and German) experiences at Dunkirk. Every business leader should study Dunkirk for key lessons on leadership.
