Hello Stephanie...if you review history you'll find that the Generals wanted to bomb Hanoi and other cities to ashes. They were over ruled by LBJ. He was concerned that the Chinese would declare war and fight with the North. China was so convinced that they were next, they moved much of their military industrial complex out of the cities into the country. They built new airbases along the border with NV and they improved the roads in NV so they could move war material to the North.
Uncle Ho was so distraught that the cities were going to be destroyed and the will of the people broken to the point where the North would lose the war. LBJ approved of every target, personally.
Review history. Had the Generals had there way the entire city of Hanoi would have been flattened first. All of it.
