Even if there is no connection to our own time, history is one of the most effective teachers of the process of empathy out there. It requires you to be able to place yourself in another time, place, and context. I'll also note that military history and "elites having dick-measuring contests" is far from the trendy side of the last four or so decades of history research and writing. Cultural history, microhistory, and even history of science are all hot topics.
