Oh, of course.
Had we given them 3 hand grenades each, the war would've turned. Suggested reading for you Tom - "The Sorrow of War". Tells the tale of the war through the eyes of a North Vietnamese soldier. I just had to read it for a class I'm taking. If the rest of the NVA went through what this man did and continued fighting for a decade, no amount of hand grenades or air support would've brought that war to an end.
You're still living in a cowboys and Indians world there pal if you somehow believe that mess was winnable.
