Not to dismiss your opinion but the truth is that if the Americans used all of their arsenal against the Vietnamese and they trained and set in more organized troops, they would absolutely have won the war. The vast majority of troops they sent were conscripts and meaning no offense but even the special ops and military planners could see a huge difference between the organized military soldier and a conscript. Also the lacking of discipline and the exposure of drugs to the army was a HUGE problem. I am by no means an American sympathizer, you country has caused more pain and suffering for our planet than any other country or empire in all of human history. However i am not stupid to the facts either. If the Americans dropped even 1 nuclear weapon on the North, you would have seen a very very different war. The Vietnamese were certainly a blooded set of warriors deserving respect. But they got to fight the Americans the way it suited them, hit and runs and guerilla war. If the yanks nuked the North and the Ho Chi Minh trail, that would have been game set and match, not to mention if they had chased the Vietnamese into Cambodia earlier in the war, as they done closer to the end of it. No, it is safe to say that the Americans would have most definitely won the war if they had done things the right ways, however that is politics.
