IIRC...
One of the main points of contention between the military (who, all differences aside, really did want to win the "war") and the politicos was that the US forces were enjoined from bombing Hanoi...or at least parts of Hanoi that would have put severe pressure on the North. The Military wanted to leverl the place...non-nuclearly, of course, but simply to reduce it to a picture resembling Dresden or Hamburg, so as to break the "enemy". The politicians would not allow that, so we ended up with what we got.
