WASHINGTON — In one of the darkest moments of the Vietnam War, the top American military commander in Saigon activated a plan in 1968 to move nuclear weapons to South Vietnam until he was overruled by President Lyndon B. Johnson, according to recently declassified documents cited in a new history of wartime presidential decisions.
The documents reveal a long-secret set of preparations by the commander, Gen. William C. Westmoreland, to have nuclear weapons at hand should American forces find themselves on the brink of defeat at Khe Sanh, one of the fiercest battles of the war.
With the approval of the American commander in the Pacific, General Westmoreland had put together a secret operation, code-named Fracture Jaw, that included moving nuclear weapons into South Vietnam so that they could be used on short notice against North Vietnamese troops.
Johnson’s national security adviser, Walt W. Rostow, alerted the president in a memorandum on White House stationery.
The president rejected the plan, and ordered a turnaround, according to Tom Johnson, then a young special assistant to the president and note-taker at the meetings on the issue, which were held in the family dining room on the second floor of the White House.
“When he learned that the planning had been set in motion, he was extraordinarily upset and forcefully sent word through Rostow, and I think directly to Westmoreland, to shut it down,” Mr. Johnson said in an interview.
He said the president’s fear was “a wider war” in which the Chinese would enter the fray, as they had in Korea in 1950.
“Johnson never fully trusted his generals,” said Mr. Johnson, who is of no relation to the president. “He had great admiration for General Westmoreland, but he didn’t want his generals to run the war.”
“Should the situation in the DMZ area change dramatically, we should be prepared to introduce weapons of greater effectiveness against massed forces,” General Westmoreland wrote in a cable that was declassified in 2014 but did not come to light until Mr. Beschloss cited it in his forthcoming book.
“Under such circumstances, I visualize that either tactical nuclear weapons or chemical agents would be active candidates for employment.”
Within four days, Admiral Sharp, the Pacific commander, wrote that he had “been briefed on the contingency plan for the employement of tactical nuclear weapons in the Khe Sanh/DMZ area which was drafted by members of our respective staffs last week in Okinawa.’’
He declared it “conceptually sound” with some minor alterations, and asked for a full plan to be forwarded to him “on an expedited basis so that the necessary supporting plans can be drawn up.”
Three days later, General Westmoreland wrote back that he had approved the plan. At the White House, Mr. Rostow noted to the president: “There are no nuclear weapons in South Vietnam. Presidential authority would be required to put them there.”
That notification led to the president’s angry eruption, and within days Admiral Sharp, once so eager to develop the plans, ordered a shutdown.
“Discontinue all planning for Fracture Jaw,” he commanded in a Feb. 12, 1968, cable to General Westmoreland, with copies to the Joint Chiefs. “Debrief all personnel with access to this planning project that there can be no disclosure of the content of the plan or knowledge that such planning was either underway or suspended.”
None of this was known to the American Marines and other soldiers who were being shelled at Khe Sanh.
“I don’t remember any discussion of atomic weapons on the ground at Khe Sanh,” Lewis M. Simons, then an Associated Press reporter on the ground with the troops, and later a Pulitzer Prize-winning reporter who worked at The Washington Post and Knight Ridder newspapers.
Mr. Beschloss’s book, which will be published on Tuesday by Crown, examines challenges facing presidents from Thomas Jefferson to George W. Bush. It also reveals that at the same time the nuclear debate was underway, senators were outraged to discover that the president and his aides had misled them about progress in the Vietnam War.
The chairman of the Senate Foreign Relations Committee, J. William Fulbright, Democrat of Arkansas, told his fellow senators that “we were just plain lied to,” and that the lying meant that the United States had lost “a form of democracy,” according to transcripts obtained by Mr. Beschloss, who is a frequent contributor to The New York Times.
There was even discussion of the possibility of impeaching the president for those lies. That discussion was terminated by Johnson’s decision, announced later that spring, not to seek re-election.
