Oh yes there are. A seditious near traitorous core of lying obsfucating anti-war activists who are trying to snatch defeat from the jaws of victory almost EXACTLY as they did to me and my comrades 36 years ago. The main difference is that they can't get away with the villification of the American soldier as they did then. For details on our military victory in Vietnam, I would refer you to UNHERALDED VICTORY: THE DEFEAT OF THE VIET CONG AND NORTH VIETNAMESE ARMY by Mark Woodruff.
See my post#40. I was there also in 68-69. My point was that OPERATIONALLY there are no simularities.
