Servant leaders typically start out at the bottom and work their way to a leadership role. This is different than those that may attend college and obtain a leadership role right out of school. A perfect example of this would be my father. He worked for Coca-Cola loading trucks. He then worked his way into a route position and then became the supervisor of sales. From there his desire the continue to lead moved him into the general manager position. His service, loyalty and passion for his job provided him the opportunity to lead verses starting out at the top. This also gain respect from his employees and had a larger following from his subordinates.
Modern day warfare is caused by the same reason as with what happened at Thermopylae when Spartans fought against Persians. The only difference between today and the past is that we are now educated people with human rights and decency. Civilizations have evolved and progressed over the years. In my own opinion, NO, it would not create the same kind of heroes as before just because of some greedy ambitions and self-interest.
Hope this helps. Have a nice day!
