Operation: ''Fracture Jaw'' was a proposed Military Tactical Plan which was created by then Commanding General of US Forces, Vietnam – General William Westmoreland.

It was unclear IF this meant the subsequent attack on North Vietnamese Cities as well. It is claimed that when The National Command Authority (The President) learned of ''Fracture Jaw'', The Plan was abandoned.
