Wars are still won by, and only by, the kid with the rifle, pistol, knife, e-tool, sharp pointy stick, or rock.
I think that most people, especially those who are too young to remember Vietnam, have forgotten that the sterile CNN wars they've been watching on TV are the EXCEPTION and NOT THE RULE.
I, too, am too young to remember Vietnam but I was fortunate enough to grow up surrounded by survivors of WWI, WWII, Korea, and Vietnam.
God bless the infantry!
