Full Auto Friday - Round 7

Today's Full Auto Friday will focus on one question, instead of multiple, with no time cap. I received a message from a man getting ready to leave active duty. He has questions about whether or not we are, or have accomplished anything with our efforts. Questions about whether or not we are the "force for good" that we say we are, whether or not the fight is worth the cost of American lives, and how to move on. They were tough questions, I hope my answers did them justice. Enjoy
