You might want to go back and research the effects of Linebacker II. We had the NV on their knees begging for us to stop. They sued for peace. We won.
After just three days all their air force was grounded. All their AA missiles were gone and they would not dare turn on their radars. Their harbors were closed and mined. All their oil stores was gone. Their logistical contacts with the Chinese were gone. The USAF and Navy aircraft were in total and complete domination of the skys. At one point even the Air Force generals were saying there were no more targets of value to hit, with the exception of the dikes. That would have just caused massive civilian casualties. I've talked to some of the POWs that were there during Linebacker II. They know.....We won!
Read your history. We won.
