Yes they bombed them, but for the most part they stayed in South Vietnam performing counterinsurgency operations, deflecting NVA attacks but never marching on Hanoi the way they'd done on Berlin decades before, why was that?
Hi! This question has come up a few times before; you may be interested in these threads:
Why was the US willing to invade North Korea in the Korean War, but wasn't willing to invade North Vietnam in the Vietnam War? (h/t u/Bernardito)
Is there a reason, during the Vietnam War, why the US never invaded North Vietnam?
Why didn't the United States use the Tet Offensive as a reason to invade North Vietnam and win the war outright? (h/t u/bleedcubsblue23)
If you still have any questions after checking out the answers in those threads, I'd be happy to answer them. So, I imagine, would the authors of those posts I linked. (Edit to provide attribution)
An occupation requires an occupying force. We had as much on our plates as we were willing to stomach. Some would argue more.
