Hardly. If we had fought VietNam like we fought WW II we would have nuked Hanoi, or at least carpet bombed it for the duration and sent the Navy and Marines in to occupy the port of Haiphong. We fought VN like the anti-WWII.
Hardly. We tried to fight a guerrila war conventionally, and it is the same thing we are doing in Iraq. There were no traditional "lines" in Vietnam the way there were in WWII. The populace did not see us as liberators and we never actually tried to conquer North Vietnam.
