I recently read an article in the Harvard Business Blog on four star general and former US top commander in Afghanistan David D. McKiernan. He was recently replaced and forced out (fired) by a new commander, General Stanley McChrystal. Basically the article states that General McKiernan was “old school” (though he was generally recognized for having done an outstanding job) and not up to speed as his predecessor in diplomatic skills, press savviness, international politics and so forth. The question I have to ask is how General McKiernan became “old school?”
