The Tet offensive proved that not only did the Viet Cong have the desire to fight back, but also the ability. It killed many US soldiers and set the war strategies back a bit. This added deeper conflict and dread to American fighters as well as American civilians.
My biggest goal in life so far is being able to make my mom/family happy. My setbacks are usually things that I do that are not so good and I disappoint. I just want another chance you know? A chance to go and stop those things.
